Attempt to perform arithmetic on local 'playerCount' (a nil value)

[alex60015]

Hello dear Rampant authors and contributors :),

While playing a (heavy?) mod-loaded multiplayer world (co-op world) with the two biggest mods being Krastorio 2 and Space Exploration, we get the very annoying non-recoverable error from the title.

The full error message:

The mod Rampant (2.0.3) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event Rampant::on_tick (ID 0)
__Rampant__/libs/ChunkPropertyUtils.lua:468: attempt to perform arithmetic on local 'playerCount' (a nil value)
stack traceback:
    __Rampant__/libs/ChunkPropertyUtils.lua:468: in function 'addPlayerToChunk'
    __Rampant__/libs/MapProcessor.lua:258: in function 'processPlayers'

After a lot of trail and error (even switching versions all the way back to 1.1.4 - where we started the world on) we found out that the error occurs starting at version 2.0.0. The first time we got the error was after a batch update of 3 libs (RitnWaterfill 1.2.0 -> 1.2.1, RitnLib 0.5.3 -> 0.5.4 & aai-industry 0.5.8 -> 0.5.9). So what we did is undo the update process and load an old save from before the update. But the error keeps annoying us. We then removed Ritn* mods and we had no problems for around... I guess 15 hours while playing and then it came back. I played a bit with the debug settings and figured out that whatever I do - the moment I move on the current save from an active chunk to an inactive one, the errors keeps happening.

I don't know if this is useless information but the last things we did was expanding to a new mine and combined with a +400 arty shot bombardment on the biters we expanded and removed a very huge amount of biter's land.

Here some more details to the error who are hopefully useful to you guys:

• savegame: https://drive.google.com/file/d/1zA_uoOIYn3dpO92empFJY0WPg7XSY29k/view?usp=sharing

I tried the savegame above on my laptop and on my desktop in single & multiplayer and both are raising the same error. If you need more details I'll gladly answer them :)

Mod setting changes:

• Startup:
  • World: Enemy Random Seed: 96325412
• Map:
  • Attack Wave: Max number of building groups that can be active at once: 35
  • Attack Wave: Max number of attack groups that can be active at once: 50

Currently we're still only on the starter planet with only some satellites in orbit, no other planets are visited so far

With kind regards Alex

Merry Christmas and sorry for opening this issue right on the 24th 😅

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