We apologize, that we missed one huge bug in the new patch related to the new maps. An old map without water was not affected at all.
Although we fixed the issue sadly all saved progress of water map can be lost and cannot be easily repaired. If you see any issue when loading your saved water-based map we recommend starting the game again. We hope you did not lose much of your time as we tried to release it asap... we still feel very sorry for that.
