Mmm yes, save points would help, maybe the option to leave and resume where you left off, instead of having to do the entire !@#$% thing over when it glitches
It's called the "Scunthorpe Problem", and Maple Story is far from the only online game that has it.
Ironically, some games have profanity filters that can even be worse, like turning "hello" into "hecko" or "teaspoon" into "teasfecesn" , or even "cl***" instead of "class" (***uming, of course, that the filter doesn't outright censor the whole message and automatically ban you from the board)
