I was playing and was at the microbe stage and I saw a massive iron chunk and ran into completely stopping me but then an auto evo cell just came and casually phased right through. I was on 0.6.7.1 on windows I’m writing this in my other device so here’s a photo of the log The log
I couldn’t get a screenshot.
That log file doesn’t seem to be from when you played Thrive as the log file doesn’t have any lines related to entering the game proper.
I think that the most likely situation was that due to the rotation of the rock the AI cell was able to go above / below it but it looked like it phased through it due to render order values (microbes render always on top of rocks even when behind them, this is a minor bug so microbe visuals have not been redone in a way that would avoid this).
