Bowie played through a v0.30 test ROM on Elmagus's GSH fundraiser stream earlier. He got as far as floor 14 before the boss death event glitched out and didn't let him go any further.
I told him I thought it was about 85% working, so that actually seems pretty accurate :3
Here is the VOD. The link should go to 8:12:03, but if it doesn't, that's where you'll find it.
Fixing this issue is top priority right now, then maybe one more test stream and a v0.30 release.
12/31 14:57 - This issue has been fixed. I was off by one on the event IDs I was calling when granting weapon orbs after bosses, so 1/8 of them would see this issue.
