Hey @cookie644, thanks for the answer. Not my game reset, only the Reset Bonus is 1. All the rest is still the same. I definitely did not clear my cookies or anything else. Manually saving is not an option and seriously, it ought to be utterly unnecessary. Since only a single piece of data is missing I suspect it wouldn't have helped anyway; it is clearly an error in the game that this data is corrupted.
Is there a way to bring back my old Reset Boost before it got set to 1? (Or at least a reasonable value, I was a bit above 1000 I think.) Currently it's a bit pointless for me to play.
Somehow my Reset Boost got reset to 1 while everything else seems untouched ... now upgrading a hobby from 43 to 44 which is already halfway through needs 647 days oO
