My spellsinger just stopped working

is my item dead forever now ???? please fix ASAP

I've been playing with my dueling wand for few days.
In my skills tab the spelsllinger is showing ! missing socketed skill with any skill socketed

This doesn't work :
-reset weapons
-reset gems
-reset game

The item seems completely bricked.
I know this exact thing happens to "cast on crit" gem, and you can discard such gems - you cannot repair it in any way.

GGG pretty huge bugs there !!!!!

Is there a workaround ?

Same here. Bricked my mirrored wand, spellsinger works only in weapon slot 2.
I had same bug with cast on crit, but somehow i fixed it with changing weapon slots in settings in comet/cast on crit, but for spellsinger i cannot find solution, i have try anything and this doesn't work.

Try check requirements manually:
1) Int requirements violation as of 0.4 sometimes not indicated by gem itself, you could update level and it silently bricks. You cna try insert another gem with lower level.
2) Check if your wand level and gem levels are not in conflict, they add some additional conditions to insertable skills and this causes massive confusion with Blasphemy (had issue with it).
3) Some gems can't be inserted anymore, one of the patches may have changed whether some skills can be inserted or not.
