First of all I want to apologise for any grammar mistakes because english is not my first language. This is the greatest map that ever existed on the workshop, it brings so much memories and it hurts to see it being infested with bugs and glitches
Here are some the glitches i came across and my ideas to fix them:

Lag spikes / map dissapearing
- (may lag a lot) render the whole map at the same time
- render a little bit more map so it reaches behind the fog

Wierd forcefields pushing vehicles / props / ragdolls with great force
- no idea how to fix, i just want to adress them so the author potentially fixes them

Guns not shooting / dealing any damage (ARC9)
-Disabling physical bullets seem to work just fine

wierd textures / zfighting
- no idea for a fix

empty map
-learn how to read and switch to the beta branch

map having no collisions
- download collisions

NPC's / Nextbots not moving
- It is impossible to navmesh or ai node an infmap

The fog annoys me so much
- type "ent_remove env_fog_controller" and r_farz 99999 in the console (there will be graphical / rendering issues)

No shadows
-maybe try making the map compatible with CSM shadows?

Random bushes water in the air
-same problem in original game, just simply delete them

Water no being wet
- water is possible in infmap, idk why its not here

if i missed something or you want me to give some video examples let me know!
