Sometimes (about 1/20) when upon spawning bot the server immediately crashes, the moment the player presses enter, Crash
other times, the server will keep going normally, and then will crash a couple minutes later, and reset back to the point when the bot was spawned Crash 2 Any ideas on what is causing this?

Most of the time its fine, and bots can be spawned and used normally

heightmap errors are from another mod, issue was occurring before it as well so it isn't the cause.
