Hey Quasi, hmm interesting update that you provided man. See. Do not know if this issue or the situation is regarding the Unzip topic. Yes when comes down to Unzipping the folder that is all alright on most people´s end. Same includes for me.
When it arrives to new versions, As there are some that not that skilled in tech areas such as myself LOL. Running into this issue may possibly happen. Where if to say, one person transfers previous versions old save files to the newest version. it is believed that would cause much issue. So this may be what is causing many issues within the game. And that is why screenshots are provided so we can assist each other mate. And RMMZ scuff?? hmm. LOL
But please feel free to tell if it does. And if there is expert advice that you can provide players. Thank You! keep up the fun work! life can be tough & busy dude. Lol.
