So I think I found a bug that rivals the banana biome for weirdest yet in 0.4.0.
After attaching flagella to my cell and leaving the editor, my game update rate tanked. It would run properly for half a second, then pause for one second, then repeat. The only part moving in real time was the cursor. Everything else - even the details of the info box - only updated sporadically.
I wondered whether there was a bug with my cell so I pressed the suicide button. After waiting an agonisingly long time for the compound cloud to disperse through all the pausing, I switched to another cell and suddenly turned into the Flash. At first I thought it was only me, but in fact the entire game was running super quick. Other cells darting about and clouds billowing equally quickly. Also of note, none of the flagella on my cell were moving.
After entering and exiting the editor again, things returned to normal, except the flagella on my cell were still broken. One was frozen and the other’s animation didn’t seem to match my movement.
So yeah. I discovered Sonic mode.
Here’s the log output if it’s of any help: https://pastebin.com/8buxyfBG
