Good morning,

I have a problem, the mod Rampant (3.0.0) caused an error.

Error while running event Rampant::on_rocket_lauched(id 10) _ Rampant _ /libs/mapUtils.lua:59: attemp to index local 'position' (a nilvalue)
stack traceback: _ Rampant _ /libs/mapUtils.lua:59 in function 'getChunkByPosition' _ Rampant _ /control.lua:649: in function
< _ Rampant _ /control.lua:642>

My current game save is there.

after about 2-3 minutes the crash comes, my two rackets are on the bottom left of the map.

I have the same problem :/

Thanks for the report.
This should be fixed in the latest version.

Crashing for me on 3.0.1 (with 248k mod also uses rockets, but I don't know if it's related)

The mod Rampant (3.0.1) caused a non-recoverable error.
Please report this error to the mod author.
