I’m playing current verson 0.6.4.1 Had already 6 cells as a structure, was in the procces of growing the second one, tried to engulf something while getting pierced by another cell when the game crashed, I don’t think i had low enough health to die but it may be related, followed instructions to report the error here

Thanks for the report. I had not seen this before.

Here’s the crash from the log:

Looking at the code I saw that I was already trying to prevent crashing due to collision index data being out of sync (it takes one extra frame for it to be updated after a colony changes shape). But I noticed that I had accidentally written index > length when I should have written index >= length. Here’s the PR that should fix the problem:
