Core.lua line 269 : local ref = strmatch(errorObject.stack, pattern)

errorObject.stack can be nil now leading to lua errors.

add anything like to your code

`
if (errorObject.stack == nil) then

		return

	end

`

i just got 3 LUA errors while starting up. No Errors During gameplay.

With the drop of the errorObject.stack == nil messages i got 0 LUA errors and no further FPS drops

it's causing huge FPS drops when zoning in

See #289.
