Hey, we have been working on this issue, it's not forgotten, just a little tricky. Quick question, when you downloaded the newest build, did you transfer in old save data from a previous build that you are trying to now load? Or are you loading from a fresh save?
Unfortunately we've found there is some incompatibility with using old save data in specific areas of the game that we have not yet found a solution for. This map was working as intended from fresh saves in previous builds though, so this info will help us figure out when the error may have started.
