From what I can tell, when you first started the game after the bug, it was still bugged from when you closed the game last. You technically have a couple thousand negative nano catalyst to get before you get to actual 0.
After you do that, it should be fine. Hasn't messed up for me again yet. Just keep playing the last mission, or play to it if you need the upgrades. That one has a TON of catalyst to collect.
