I was creating a mod which adds a few new weapons into the game, when i was done, i opened the game to try out the mod but when i load up a map, it crashes when the loading gets to 15%, and when i check out the rwr_game log, the last few lines are

11:57:09: : map config weapons loaded
11:57:10: : CHECK: unset loading failed
11:57:10: : execution halted
11:57:10: : uninit comms

I swear i added the weapons to all_weapons.xml and when that didn't work, i just created the new weapons with vanilla weapon files but to no avail, anyone who has any idea please help.

Did you add the weapons that are new to the specific factions they are owned by. There could've been a typo in the code for one of the weapons as well. Or the weapon key you typed in to the all_weapons.xml may be incorrect.

For example you may of typed(copy and pasted) this:

<weapon key="benelli_m4.weapon" />

when its supposed to be this

<weapon file="benelli_m4.weapon" />

thanks for the help, it was settled
