I must Use Game Version 1.0 Rampant 1.0

When i use the Command /SetRampantAISurface Factory Floor 1 Command Crash the Game

The Problem is the Rampant Mod for Game Version 1.0

Error Log:

Rampant/Lobs/PhermoneUtils.Lua:113:attempt to index local "chunk" (a nil value)
stack traceback:
Rampant__libs/PhermoneUtils.Lua:113: in function processStaticPheromone
__Rampant__libs/MapProcessor.lua:171:in function processStaticMap
__Rampant/control.lua:1307: in function
Rampant/control.lua:1290

First Question: What doing this Command?
And The other Question is: need i the Command /SetRampantAISurface or i can ignore this Warning, when i go in any Factorissimo2 Building?

This looks like an issue I probably can't do anything about. You should report this to the Rampant mod.

ok i doing this thanks
