Thank you! That works.
uh, I knew the properties were different, but to use that particular token the fastest way was to download it, drop it in and then manually set the properties.
Or at least it would have been the fast way if I didn't incurr in that little problem (Which made me lose half an hour of unsaved modifications. Yeah I should save more regularly XD).
Now I think I understand what caused the problem.
So, if I were to make sure my properties aren't sharing names, like in this case that "HPMax", they wouldn't be pasted in my campaign and so they wouldn't create issues, right?
