Crash on level 100 artifact realm

When selecting to return to Siralim


############################################################################################
FATAL ERROR in
action number 1
of Key Press Event for E-key Key

Also, this is my 99% artifact:

Is that kind of boost intended?

And I believe I had 2 portal keys when I entered, but I lost both instead of one.

Also, the numbers on “view artifact” and the actual stats it gives are different

it’s still happening (the stats, not the crash).
