Apologies, I haven't actually checked for duplicates; I'm new to github.

How to reproduce the issue

Import https://pobb.in/PGe612W9HKXh
Items: select Weapon Set: II
Main Skill: select second Icestorm (the one with Cast While Channeling)
Skills: select Icestorm (Active [in green])
Skills: select at top (one with Conc Effect and Arcane surge)
Left click on the spell line just below Arcane Surge.
Crash.

Some of the above may not be needed. The list is short enough though I didn't bother to try to reduce it.

This appears to be caused by an issue with the cross linking logic. The skills selection drop down only seems to consider supports from the same skill group and cast on crit depends on a property from the support which is applied to the triggering skill.
