Two other things bug-related:

1. As Tsagoth has noted above, the black holes are not being properly recorded on your victory progress in game, but should be counting towards your victory behind the scenes. I recommend keeping track of your progress yourself and report any strange behavior as a bug.

2. This is one can be very frustrating, but if the server restarts aor goes down, then the progess on the solar core taps is lost, meaning that you will then need to restart any that did not run for the full 24 hours. I also noticed a problem that after 24 hours of running, they may not actually turn the sun into a blackhole, but this may have been a unique problem on Belitlli due to a number of server crashes while I was making blackholes. Another possible explanation is that I sometimes turned on cloaking before starting the core taps. This is for another thread, but cloaking may have some problems associated with it.
