I tried all the versions and I can't find one compatible with GunGame for hl. The plugin is working but it doesn't refill the ammo for the weapons.

Same issue for the BugfixedHL version 1.5.1 . The only version I could find to work is bugfixed.HL.0.1.910.
So, I think is something wrong in the .dll and .so file (tested on Windows and Linux)
