Nexus Clash

My Seraph (ID 14044) stepped outside to go hunting but when he was up there he noticed it was day, so I went to go round up some work. When I came back 2 ticks later he's still flying (not gliding or landed, as I'd expected).

Was watching on the tick when I had a flying potion active and it showed gliding for a single page refresh and then flipped back to flying.
