My world has no issue loading or working but can only handle about 5 minutes around my house before all the static blocks disappear then the game crashes. the error message reads 'minecraft has run out of memory' and suggests that it is caused by a bug or not enough allocated space. i have increased the memory so i don't believe its that, does anyone know of any bugs that may be causing this? maybe specific items together in the same chest or a mod not working correctly? i have screenshots and bug reports if they are any use Any help is massively appreciated, thanks
