I've modded the Total War series since Rome so I'm not new to the game, but this problem is stumping the hell out of me. Any file I take from patch3 to change and add to my own mod crashes the game during startup. Taking the same file from patch2/patch1/patch/vanilla works exactly as it should, without crashes.
For example, if I extract unit_stats_land from patch3 with the PFM, add it to my own mod, and, say, change grenadiers so they can't use grenades, the game crashes during startup. If I take the exact same file from patch2 and make these changes, the game runs fine. This occurs for other files as well from patch3.
Patch3 itself is functioning perfectly in the vanilla game; there doesn't seem to be anything wrong with it. I've obtained other copies of the patch and compared them and they're all exactly the same, so I don't think the patch itself is the problem.
Anyone see this before? Or should I just reinstall and start from scratch?
