why do i suddenly have over 50 gothimorphosis crystals???

[LavenderInk]

I didn't see any event giving me so many, it seems so extreme anyway. What happened? Did I miss something? I'm not going to use them as long as there's the possibility it's a glitch/bug.

When you reach 30 or made a new one, often the game glitch and load 50/30 crystals, if you refresh your page or try to made one gothimorphosis, it return to normal value (normally) ^^

It may be linked with the bug on the background gift, I gained more than 30 crystals too but I didn't touch my mine today
