One of my players has run into a bug with his Strength score that has made the whole sheet get weird. It all started when he tried to edit his Strength score because he drank a Potion of Storm Giant Strength: I managed to fix his sheet by directly editing the @{strength} and @{strength_flag} fields then forcing the sheet to recalculate things based on his Str mod (Str save, Athletics check, weapon attacks), however, now it keeps happening. Most recently, it happened when he tried to level up. I have tried to create a fresh duplicate of the sheet, thinking perhaps some bugged text got inserted somewhere that the sheet workers are chewing on and dying. I only copied descriptive text, dragged items from the compendium, and typed values manually, in order to replicate the sheet, I did not hit the Duplicate button. Once I was finished, the duplicate sheet began experiencing the same bug. This thread from 2 years ago appears to be suffering a similar bug, affecting a character's Dexterity score: <a href="https://app.roll20.net/forum/post/9439455/slug%7D" rel="nofollow">https://app.roll20.net/forum/post/9439455/slug%7D</a> However, there is no resolution there. I have managed to confirm that whenever the bug triggers, any weapons with an entry in the attacks repeating section have their MODS field wig out as well. The last 1-2 items in the MODS field list get duplicated or triplicated or more. I first noticed when I saw that the character's Sun Blade had 133 copies of "Attacks: 2, Damage: 2" at the end of the MODS field. Deleting the extra mods and triggering the bug again causes more duplicate MODS to be created, presumably repeating each and every time the bug occurs, and it happens only to weapons with attack entries, not to weapons without them. Before triggering the bug: After triggering the bug: In this case, Sun Blade and Waythe both have entries in the attacks repeating section, while the other weapons in the character's inventory don't. Sometimes, I can trigger the bug by putting a value in the @{strength_bonus} field (which is how my player triggered it in the first place). But I have also had it trigger just editing an attack or item, and my player triggered it while leveling up from 13 to 14 and taking Resilient (Dex). Any ideas to stop this happening would be appreciated.
