That sucks. Didn't even realised that. I always used the free day from next episode for upgrading. Simply beacuse I don't have time doing both things with battling bosses and upgrading. And first time I ran out of credits, the biggest amount I ever had was 5 billion.

Luckily I never used much transmetal, and have ben saving them from their beginning for a crysis like that.
