Sometimes I don't see my mod on the In-Game background loading page.
It's my first time making me think that my mod has an error.
The results show that it is not a problem with my mod.

Therefore, if you have a problem like me Try following me as follows:
1) Go to your Steam Page
2) Go to LIBRARY and select GAME
3) Right click on the Insurgency game icon and select Properties
4) Select the LOCAL FILES tab
5) You will see the word Verify Integrity Of Game Files...
Click to check your game files
After that, wait until it has finished checking
6) Try enter the game

P.S. I don't know if it is everyone. But I advise to try first
