 ## #146 — Building/house-wall collision lost after portaling INTO a town (works on fresh login)
 
-**Status:** OPEN
+**Status:** DONE (`49d743f`, 2026-06-24) — root confirmed via the `bldOrigin` probe (Holtburg shell cached at the Arwic frame, ~5.5 km off) and fixed by re-basing the building cache on each landblock apply (`PhysicsDataCache.RemoveBuildingsForLandblock` + clear-then-repopulate in `ApplyLoadedTerrain`). Verified on the exact repro (Arwic login → Holtburg portal): `bldOrigin` now at the wall, channel returns `Collided`/`Slid`; suites green. (Move to Recently closed on next tidy.)
 **Severity:** MEDIUM (clip through house/building walls after every portal-in; doors still block; terrain solid)
 **Filed:** 2026-06-24
 **Component:** physics — building collision channel + streaming-relative frame (teleport recenter)
