tacit glacier
I just hit level 5 with la reina and you can see it doesn't give the proper preview of what's next. I did double check my inventory and I got her icon and 2nd taunt as I should have (assuming the bucks and coins as well?) so it's hopefully just a visual bug.
fallen vortex
Issue is still present in current patch
grave relic
for me too );
tacit glacier
I can still level up (currently lvl 13) but it won't show the correct icons for the rewards
burnt dune
Last patch, it seemed like the experience from La Reina's arcade also didn't count until you gained experience in a normal battle. That might've been fixed, but I feel like I should mention it anyway.
