1-Before reporting an error you should test if the error persists by loading only "Females-TCGM_Girls", "CTRG 2035 Expansion Pack" and "TCGM_CTRG-2035_Girls". If the error does not occur, it means that it is due to an incompatibility with some other mod.

2-To detect which other mod is causing conflict and making a bug, you can use the halves method. Load only half of the mods that you usually use together with "Females-TCGM_Girls", "CTRG 2035 Expansion Pack" and "CGM_CTRG-2035_Girls", open the game and do some tests. If the error occurs, the incompatible mod is in that half. If so, close the game and discard half of the mods again (now you will have loaded only a quarter of the mods that you usually use, always remember to keep my mods and the "CTRG 2035 Expansion Pack" loaded), open the game and check again. If the error does not occur, it is because it is not in that half. Then you should load half of the other mods and check. If you use this method well in about 8 steps, you will discover which one is giving you problems.

3-Once you identify which mod is causing conflicts, try to put it higher in the mods list of the Arma3 Launcher so that it loads first. Commonly the order in which mods are loaded can affect their performance. If you put a mod on your list first that requires another and put the required mod below, that may cause an error message to appear and the mods may not work correctly for you.

4-If the problem persists, contact the creator of the other mod to report the bug.
Obviously you can also inform me which is the mod that is causing problems so that I can do some tests and see if I can solve it.

5-If you don't get a response or the author of the other mod has no intention of doing anything to repair the incompatibility, you can choose to discard their mod from your list. That will also solve your problem.

6-The "T" pose bug is fixed by restarting the game. It's just a loading error and it happens very occasionally the first time you load a mod. Is a common Arma3 bug is not from the mod.
