I was wondering what is happening to the game and it's creator. It's been several months now without news or updates, I really hope everything is alright.
Thank you for the answer, I can rest reassured now that the project hasn't come to an end.
Also, it's great to see that you're going to have more time for the development soon.
No problem at all, I mean, that's what an Alpha is for after all, isn't it?
The crashes happened after leeting the game run while going afk for a while and coming back after about 10 or more minutes. Reloading the game doesn't solve the issue, need to restart the world from scratch. Maybe this might help you troubleshoot the issue.
