That's current free version, and I got it only one time , second time I didn't have issues, probably because second time was not in exploration zone
It's a game crash, so it's a rather big problem for the player. Anyway, I just tested out the scene in the first exploration zone, and it runs correctly for me. Looks like we need to see your saves to troubleshoot this properly. Zip your entire save folder and send it tome via yeehawgames@gmail.com
Also, did you use any cheats or save editing tools before the problem?
