I'm trying to play stardew multiplayer with some mods I recently updated for 1.6, but it keeps telling me 

[SMAPI] An error occurred in the overridden update loop: InvalidOperationException: Failed reading Character (Farmer) field 'Character (Farmer): friendshipData' ---> InvalidOperationException: Failed reading Friendship field 'Friendship: __instance.get_questionsAsked()' ---> InvalidOperationException: Operation is not valid due to the current state of the object. at Netcode.NetRefTypes.ReadGenericType(BinaryReader reader) in D:\GitlabRunner\builds\Gq5qA5P4\1\ConcernedApe\stardewvalley\Farmer\Farmer\Network\NetFields\NetRef.cs:line 368 at Netcode.NetRefTypes.ReadType(BinaryReader reader) in D:\GitlabRunner\builds\Gq5qA5P4\1\ConcernedApe\stardewvalley\Farmer\Farmer\Network\NetFields\NetRef.cs:line 345 at Netcode.NetRefBase`2.ReadFull(BinaryReader reader, NetVersion version) in D:\GitlabRunner\builds\Gq5qA5P4\1\ConcernedApe\stardewvalley\Farmer\Farmer\Network\NetFields\NetRef.cs:line 221 at Netcode.NetList`2.ReadFull(BinaryReader reader, NetVersion version) in D:\GitlabRunner\builds\Gq5qA5P4\1\ConcernedApe\stardewvalley\Farmer\Farmer\Network\NetFields\NetList.cs:line 277 at Netcode.NetFields.ReadFull(BinaryReader reader, NetVersion version) in D:\GitlabRunner\builds\Gq5qA5P4\1\ConcernedApe\stardewvalley\Farmer\Farmer\Network\NetFields\NetFields.cs:line 236 --- End of inner exception stack trace --- at Netcode.NetFields.ReadFull(BinaryReader reader, NetVersion version) in D:\GitlabRunner\builds\Gq5qA5P4\1\ConcernedApe\stardewvalley\Farmer\Farmer\Network\NetFields\NetFields.cs:line 240 at Netcode.NetExtendableRef`2.ReadValueFull(T value, BinaryReader reader, NetVersion version) in D:\GitlabRunner\builds\Gq5qA5P4\1\ConcernedApe\stardewvalley\Farmer\Farmer\Network\NetFields\NetRef.cs:line 264 at Netcode.NetRefBase`2.ReadFull(BinaryReader reader, NetVersion version) in D:\GitlabRunner\builds\Gq5qA5P4\1\ConcernedApe\stardewvalley\Farmer\Farmer\Network\NetFields\NetRef.cs:line 223 at Netcode.NetDictionary`5.ReadFieldFull(BinaryReader reader, NetVersion version) in D:\GitlabRunner\builds\Gq5qA5P4\1\ConcernedApe\stardewvalley\Farmer\Farmer\Network\NetFields\NetDictionary.cs:line 426 at Netcode.NetDictionary`5.ReadFull(BinaryReader reader, NetVersion version) in D:\GitlabRunner\builds\Gq5qA5P4\1\ConcernedApe\stardewvalley\Farmer\Farmer\Network\NetFields\NetDictionary.cs:line 603 at Netcode.NetFields.ReadFull(BinaryReader reader, NetVersion version) in D:\GitlabRunner\builds\Gq5qA5P4\1\ConcernedApe\stardewvalley\Farmer\Farmer\Network\NetFields\NetFields.cs:line 236 --- End of inner exception stack trace --- at Netcode.NetFields.ReadFull(BinaryReader reader, NetVersion version) in D:\GitlabRunner\builds\Gq5qA5P4\1\ConcernedApe\stardewvalley\Farmer\Farmer\Network\NetFields\NetFields.cs:line 240 at Netcode.NetExtendableRef`2.ReadValueFull(T value, BinaryReader reader, NetVersion version) in D:\GitlabRunner\builds\Gq5qA5P4\1\ConcernedApe\stardewvalley\Farmer\Farmer\Network\NetFields\NetRef.cs:line 264 at Netcode.NetRefBase`2.ReadFull(BinaryReader reader, NetVersion version) in D:\GitlabRunner\builds\Gq5qA5P4\1\ConcernedApe\stardewvalley\Farmer\Farmer\Network\NetFields\NetRef.cs:line 223 at StardewValley.Multiplayer.readFarmer(BinaryReader reader) in D:\GitlabRunner\builds\Gq5qA5P4\1\ConcernedApe\stardewvalley\Farmer\Farmer\Network\Multiplayer.cs:line 892 at StardewValley.Network.Client.receiveServerIntroduction(BinaryReader msg) in D:\GitlabRunner\builds\Gq5qA5P4\1\ConcernedApe\stardewvalley\Farmer\Farmer\Network\Client.cs:line 303 at StardewModdingAPI.Framework.SMultiplayer.OnClientProcessingMessage(IncomingMessage message, Action`1 sendMessage, Action resume) in SMAPI\Framework\SMultiplayer.cs:line 305 at StardewValley.SDKs.Steam.SteamNetClient.receiveMessagesImpl() in D:\GitlabRunner\builds\Gq5qA5P4\1\ConcernedApe\stardewvalley\Farmer\Farmer\SDKs\Steam\SteamNetClient.cs:line 406 at StardewValley.Network.Client.receiveMessages() in D:\GitlabRunner\builds\Gq5qA5P4\1\ConcernedApe\stardewvalley\Farmer\Farmer\Network\Client.cs:line 70 at StardewValley.Menus.FarmhandMenu.update(GameTime time) in D:\GitlabRunner\builds\Gq5qA5P4\1\ConcernedApe\stardewvalley\Farmer\Farmer\Menus\FarmhandMenu.cs:line 292 at StardewValley.Menus.TitleMenu.update(GameTime time) in D:\GitlabRunner\builds\Gq5qA5P4\1\ConcernedApe\stardewvalley\Farmer\Farmer\Menus\TitleMenu.cs:line 1728 at StardewValley.Game1.updateActiveMenu(GameTime gameTime) in D:\GitlabRunner\builds\Gq5qA5P4\1\ConcernedApe\stardewvalley\Farmer\Farmer\Game1.cs:line 4795 at StardewValley.Game1._update(GameTime gameTime) in D:\GitlabRunner\builds\Gq5qA5P4\1\ConcernedApe\stardewvalley\Farmer\Farmer\Game1.cs:line 4117 at StardewValley.Game1.Update(GameTime gameTime) in D:\GitlabRunner\builds\Gq5qA5P4\1\ConcernedApe\stardewvalley\Farmer\Farmer\Game1.cs:line 3185 at StardewModdingAPI.Framework.SCore.OnPlayerInstanceUpdating(SGame instance, GameTime gameTime, Action runUpdate) in SMAPI\Framework\SCore.cs:line 707
