[AT THE START SORRY FOR MY BAD ENGLISH]
Hey, i want to make a Zombie survival server and i created my own map who stand's for safe zone. But there is one problem, if i make a one step, many objects are just invisible. Another thing, this happens only on my own serwer, at the map editor "F5" Test everything is fine but when i start my own serwer at the MTA>SERVER>MTA Server.exe my map doing that strange things... And that happens only at that tunnel, at the station exit everything works... The question is, can i fix that or just forget about my lost time at that map?
Help me please...
