GUYS!!!! STOP SAYING THIS IS THE FIRST SAVE!!!! THe "REAL" first save from when tpt was made was deleted after a major update, and during that update every save was deleted. So, this save is accutaly a "First save" AFTER the update, so you can't call this "The First save in tpt".
IS DIS DA FIRST SAVE???!!!! (save id = 1)
Guys, the reason things do not melt on this save is because the heat simulation setting is turned off. Press the settings button and things will melt again. Nothing is broken.
