Thanks! I did not check that one, and I'm on a European system xDJoseph Staleknight wrote:You did check if your computer's decimal system runs on the European system (1.234,56), right? That issue pops up a lot on computers that use that notation, since SMBX prefers the American system (1,234.56). Basically, you should swap the decimal and thousands separators in your Regional settings so that the latter notation is used, otherwise SMBX will panic and hide in the corner like someone who just saw Slenderman brush his nonexistent teeth.
EDIT: Or you can go to the offending level's folder, open up all the "npc-xx.txt" and/or "lunadll.txt" files and replace every decimal point with a comma, but that's more tedious since I imagine a lot of levels use periods to separate decimals in their text files. Hope that helps!
*And it works! Just had to change decimals from , to . like you said.
