That’s excellent. Could you send me the file again (maybe a PM if there’s a download limit or something)? It says it is deleted already and I didn’t download it yet.
Okay so after reading the code again turns out that I had forgotten half of the colony handling logic. I had only implemented a colony engulfing things resolving to the actual cell that should do the engulf, but I had forgotten to check and resolve the engulfing target to the real cell in case the target was a cell colony. So that’s why the other cell always grabbed your colony lead cell: there simply was no logic to check if a engulfing target was in a colony and act accordingly, it just always assumed the thing to engulf was just a single cell. And that’s the root cause for the bug.
I’ve made a change to fix this:
With the fix using your save, the other cell can no longer engulf the player out of the colony. And it cannot engulf any of the wall cells due to being just barely too small to do that.
