I have a mod that edits the TEC kodiaks and I have edited the FrigateTechHeavy.entity and put it in the game info folder and also the manifest as
entityName "FrigateTechHeavy.entity" (entity count is correct too). But sins freezes (no minidump, just stops responding) when I try to use this mod.

I also have the entrenchment conversion of bailknight and the converted "frontiers" version of the sins plus mod. The file editing is done within the frontiers mod folder. I don't think the problem is the entity manifest file, so what could it be?

Edit: I tried disabling bailknight and trying to use a frigatetechheavy file pulled straight from the forge tools references and it still does not work, so the problem isn't related to the modding of the file or to bailknight.
