You can update your game with patch from devs subscribestar, just make sure you updating previous version of the game (like 0.48 --> 0.49), so there won't be need to download full game every update
That's the thing, I couldn't download the previous updates neither, because they're too big of a file for my potato laptop to handle, chief. :(
Funny story, I tried to take a detour around it the other day, and guess what? The USB drive I was using to download the 12 GB .rar folder LITERALLY crashed and my pc now fails to detect it as an external storage device, preventing me from accessing any other files on it from now on, practically forcing me to either seek services from professionals or scrounge the internet for advice, cuz I'm at a complete loss as for how to fix it.
