The revision of Hotfix #32 is 852257
Changelog
Fixed an issue that could lead to black flickering artifacts or a void filling out the screen.
Fixed an issue that under specific circumstances could lead to a broken save game where the flame altars could no longer be saved correctly.
Important Note:
IF YOU ENCOUNTERED THE MISSING BASE/FLAME ALTARS ISSUE, YOU NEED TO TAKE ACTION.
Please immediately back up your save data (this means copy the save folder somewhere else for safekeeping) and perform a roll-back to an older copy of your save. Help for how to do so can be found in this support article. If you're not sure how to do that, please contact our support team via the same link by clicking "Submit a request".
DO NOT KEEP PLAYING ON A BROKEN SAVE AS THE BACK UP SYSTEM WILL EVENTUALLY OVERWRITE OLDER, RECOVERABLE VERSIONS OF YOUR WORLD WITH THE NEW BROKEN ONE.
