Me too

The mod is working for me. The flask icon can be kinda hard to spot. It appears during a run in the upper right corner.

Nothing seems to be happening at all is there some button to press?

for me its the same

Works perfectly. Enable mod, start new game, click flask on top right.

the flask doesnt apear for me

was working for me yesterday but today my wand no longer shoots unless i disable the mod

I too was confused when there didn't seem to be any change after enabling the mod, but there indeed is a flask icon on the upper right corner of the screen. You do have to start a run to have the icon appear

Main or Beta branch?

For me the fix was to rename the mod folder to spell_lab

You have to go to the mod menu and enable it first (start screen > Mods > Spell Lab > enable > back to start screen> Flask in upper right corner)

I have the flask icon hidden problem too.
Then I stop the other mods as many as I can.
Resubscribe this lab mod.
Problem solved.

This mod seems to be incompatible with Thematic Random Starts, enabling that mod seems to make the flask button disappear.

my wand no longer shoots unless i disable the mod

the mod kinda works, theres a lot of missing spells for me, even ones i know i have unlocked
