In response to post #22135034. #22136349 is also a reply to the same post. After installing large files (Interesting NPC-s does it for me and is the largest mod file I use) I get this issue. The program has a general lag to it after installation- scrolling, adding files, commands, button presses etc all have a 3-4 second delay to them. Problem stays even after restarting the program. If I uninstall Interesting NPC-s the problem goes away and am able to finish modding my game with other files just fine. This is just with the 0.60.0a build by the way, the stable release works fine.
