Hello,
Sorry to hear this!
So that I can try to investigate your issue further, would you mind sending across your Two Point Museum folder? To do so follow this navigation path in file explorer: C:\Users\<username>\AppData\LocalLow\Two Point Studios\Two Point Museum. Once located, "Zip" the folder up (right click and you should see the option).
Zipping a folder is a way of compressing it into a smaller size. If you don't have an option to do this, you may need to download a program to help. I use one called 7zip which can be obtained here. The top option - ".exe - 64bit windows..." should do the trick. Once zipped up, you can attach it to your reply.
I can also point you towards some steps here that explain how to try and restore back up saves, which might help you continue to play. Just remember to back everything up if you do attempt to restore one of your saves.
Thanks,
Chizel
I have about 22 hours into the game, and I'm loving it so much! I loved the previous two titles also! But today when I played the game crashed on my twice in a row. The third time I opened it my save file was gone and I lost everything.
