assets are constantly in the process of being restored since the start of the project (for example only 5 out of 18 hamsters and 7 out of 46 ball designs currently have their original textures), it just takes a long long time as a passion project and depends on the volunteers.
if you want a more detailed look at what was restored / found, have a look at our assets sheet: https://docs.google.com/spreadsheets/d/1Znqm_JfIegcUbT4adxkU_Zqwpn-nvqtxxNbCYUueWcI/edit?usp=sharing
we also got a big source of collected pictures from the base game for references if you're curious: https://www.pinterest.com/MarrowBird/found-mazin-hamster-images/
regarding the bugs
about the You are leaving the zone text, it was blue in the original version so its correct.
the misplaced trampoline under the ground is not a mistake, i already looked 20 times into it when i placed it and it seems that in the original version there was just a misplaced one, the way i remade the hamlet zones is very precise, if an object is somewhere theres a 99% chance it belongs there. why is it there? no idea, maybe a scrapped part of the cave system
about everything else, i hopefully can include fixes for those in a patch in a few weeks
