Thanks for looking more into it. Yeah ants carrying food will switch to feeding larva if there are new larva that need to be fed. The example you sent in these screenshots seems like it might be a different issue... or I didn't properly understand the original issue.
I wonder if the next time you run into this, you can pause, then open the console and enter:
JSON.stringify(store.getState().game)
which will dump the game state into a giant string that you could share with me via like pastebin.com or something I can try to mess around with it? I've never actually transferred the game state that way but it just miiight work haha
