My game keeps exiting randomly for what to me is no apparent reason. Before crashing I often get a bit of foretelling, blocks fail to update properly, for example if I destroy a block, a "ghost" image will remain. Soon after this the game will crash. However, I have gotten the same error without interacting with blocks.
The game seems to run at a much lower performance than I would expect from my system and previous sessions, even with the current update (Back when I first updated it ran fine). Sometimes I try to monitor the performance using debug [F3], and I notice that the game although starts at a 10%-30% memory consumption can sometimes get around 40%-50%. The game also has very frequent spikes in lag and frame rate loss.
Well, it seems the problem is related to one of my world saves. I started a new save yesterday and other than the usual slowdown due to initial world generation, everything seemed to be fine. I suppose the question now is if my previous world could somehow be saved, and if I could find what exactly is causing this in the files...? I have posted the save up, if anyone wants to try and confirm or my problem or try to fix the files.
