Ostranauts v0.8.0.13 is now available on Steam, and your clients should be updating shortly.
This patch fixes several bugs that have been reported recently, plus rebalances some things and makes a few economy changes. (And we're still working on a larger update in parallel for the next milestone.)
Saves from 0.8.0.X should work. If you were experiencing issues in the older save, this patch may fix some (especially timing-related issues), but others may persist depending on the cause.
