Crash attempting to save with an Envy tag

[Skelebrolo]

Winning the game or closing to Main Menu with an Envy tag crashes the game. I hypothesize this is because SMODS fails to evaluate the function within the Envy tag when the variable G.jokers.cards is not loaded.
if #G.jokers.cards > 0 then seems to cause an index of nil only on save, not on initialization. Setting this "if" statement to True seems to save the Envy tag without issue.

Oops! The game crashed:
[SMODS entr "items/inversions/reverse_runes.lua"]:399: attempt to index field 'jokers' (a nil value)
