Conflict between yet another mech and yet another weapon

[Toldekk]

I recently added yet another mech. I have been trying to replace all the mod files that I had removed sometime ago. I finally remembered the last two that I was looking for. I installed the "yet another mech" into my mods folder and all was good, except for a message of small weapon placehoder or some such message when I went to view market items. I found and installed yet another weapon and for once did it properly on the first go. When I activated it in the mods folder it said that there was a conflict with yet another mech. Is there a fix for this, what can I do.

Any help is welcome, thank you for your time.
