hi Gauss, thanks for the quick reply. I'm using the Pathfidner Second Edition by Roll20 The character sheet is being used as such : Adjusting Max HP by adding the ancestry value, the class value and any "other" values needed. and setting the characters level to the appropriate level (this time it's level 6 at the moment) Then make their tokens, imputting the pictures and click-dragging them onto the board. Adjusting them to represent the correct character, have the bar set to the hit_points. visible by all, compact, bottom overlapping. In game we would select the token and click the circle for the relevant bar and adjust the HP value there, which beforehand has adjusted HP normally between character sheet + token. reflecting the changes made between both. This session, when doing so, it would reduce the maximum HP to 0 after adjusting the current HP. My Oracle player's sheet, for an unknown reason, displays his maximum HP at 0. (screenshot included). Both adjusting the HP from sheet or token provided the same result for myself and one of the players. Reappling the settings and resaving did not solve the issue. It simply returned to 0 hp after the next time they took damage.
