@ThunderSt(View Post) Maybe ask Simon about the thumbnail problem, he might have broke something when resetting all the thumbnails. Also, the second one has always been happening. Saving and loading render options with saves would fix it, my mod does it, but I don't think official does.
@cyberdragon442(View Post) If people see a save that's just a block of diamond, they probably won't open it. It's too prevent that, since that's not what the game is designed for. There are probably better ways to deal with it, but this is easiest and appears to be working (Although I never noticed big problem at all before, the other moderators said they were removing saves like that all the time from the front page).
@cyberdragon442(View Post) if u use console (Ex. tpt.el.dmnd.color=0xff0000) then only you will see the difference, and the changes will go away as soon as u exit tpt. If u use something like "tpt.set_property("dcolour",0xffff0000,dmnd)", then it would be the same as using deco. Have you tried void, prti, heated filt, heated wifi, powered void, tnt, or just uses only a little deco instead of getting rid of it all, for your only one red element problem?
