[Edit] :This issue is resolved in 4.0.2. Thanks for the quick turn around!
Heya, we use both of the critical extensions in FGC, with the latest version from here, our barbarian can't land melee damage. We get
[3/5/2021 10:06:26 PM] [ERROR] Handler error: [string "scripts/5E-Theogeek-Nat20.lua"]:300: attempt to index field '?' (a nil value)
when we try to roll damage. Non-critical, she is raging, great weapon master, reckless attack.
Turned off all her effects and it works.
With Rage on it does not work.
With Great weapon master on it does not work.
Basically, can't roll damage when either Rage and/or great weapon master is on.
