A building's pool drew forever once its room had been visited, and a portal-less building with an area id never drew its pool, Northshire Abbey's wall fountain among them. In 1.12.1 the flood's visit `0x685d70` links a visited group into the liquid list (`0x685f6b`, the only link), and the liquid pass `0x684cd0` unlinks each record as it draws (`0x684e1d`). So a pool draws exactly in the frames its group is visited. The latch is gone, and the fountain draws. Across 184,624 camera poses around the Great Forge, benilla's flood keeps the lava wherever the reference's portal graph does.
A pool's liquid type read every tile row and the group's override. `0x6ba970` scans only the first row and takes the first wet nibble, and its caller never reads the override. benilla now does the same.
`WOW_LIQUID_TRACE=1` prints each pool's per-frame verdict.
