Randomly changing stat values

Hey In one of my 5e games, I've been having my characters stats jump from their bases values to around 1610100. I'm not entirely sure why it keeps happening but this time it happened, it happened when I was using the older sheet and adding a additional damage modifier. It does this to two stats my, strength and my wisdom and I don't know why. Its very time consuming trying to fix the issue as I need to go through and scrub all of the values or it doesn't go away and just goes back and resets all my work to correct it. I have only added two different values for 2024 Shillelagh; [[ {8 + 2*(floor((@{level}-1)/4)),12}kl1*(1 - floor((@{level}-17+100)/100)) + 6*(floor((@{level}-17+100)/100)) ]] ShillelaghDiceCount [[ {1 + floor((@{level}-17+100)/100),2}kl1 ]]

Hi Edvardo,  Which character sheet are you using? If you don't know the name please supply a screenshot. 

Hello Gauss The character sheet I'm currently using is the D&D 5e 2014 sheet, unless you mean the character's name on the sheet.

Ok, so this is a known issue of the D&D 5e 2014 by Roll20 character sheet. What you do is go through all your inventory and remove the checkbox on all of it until you see which inventory item is causing it.  Then delete that item.  Then tell me which item it is and I will tell you how to add it back without it being likely to bug out again.

That's the most bazar thing, it was a normal quarter staff of all items doing it.

What can happen is the mods line of an item gets corrupted. What you do from here is add the item in manually. Do not drag/drop from the Compendium.  If it is a weapon do NOT click the attack box (you should never click the attack box, always put in weapons manually in both equipment and attacks, they get bugs if you do it via the Compendium). Then make the attack manually.  If there are any stat modifiers in the mods line we can add those in manually and they should not get bugged out. Let me know if you need a stat modified and which one it is.

Yep that fixed it, thanks for the help, I don't think it would have been that out of all things honestly. Thanks for the help.
