Describe the bug
I used Wyrmhole Generator: Dragon Isles at Gadgetzan and got this error:

1x ...ns/InteractiveWormholes/libs/Dashi/modules/event.lua:121: ...Ons/InteractiveWormholes/libs/Dashi/modules/misc.lua:138: bad argument #1 to '(for generator)' (table expected, got nil)
[string "=[C]"]: in function error' [string "@InteractiveWormholes/libs/Dashi/modules/event.lua"]:121: in function TriggerEvent'
[string "@InteractiveWormholes/libs/Dashi/modules/event.lua"]:132: in function <...ns/InteractiveWormholes/libs/Dashi/modules/event.lua:131>

Locals:
