From 2.1.1's Sentry reports (60,000 in three days, 2026-10-21): - Textures: a stale render texture handle takes the game's default texture instead of reading through null (Skate.exe+0x3e897fb, a third of all reports, every one with TheVlixOne-Nike_Pack 2.3.x). - Physics: the wake pass's bitset is made as long as the world's owner list once indices pass 20000, after long multiplayer sessions (+0x3d99e2f, +0x3d9ee43, +0x3d9ee47). - Music: more than 1024 candidates are picked by ReSkate; the game's shuffle wrote past its stack table. - Streaming: a staged read's piece that reaches past its 64 KB buffer is left unfilled (VCRUNTIME memcpy). - Multiplayer: a remote skater or board whose parent bus link is damaged is left alive instead of destroyed (+0x2b94cd0). - Mesh pool: on an integrated GPU its budget is capped by the RAM and page file free; the Memory line says what the PC has left. Launcher: - A folder with non-ASCII letters is a hard stop (the boot crash +0x18df4cf came after "Start anyway"). - The game's data files are checked against the supported build's sizes (from Steam's manifest); missing, cut-short or online-only files send the player to verifying. - One game per folder: the launcher will not merge or start while one runs there, and ReSkate.dll holds the folder's mutex. - Advice on the ready screen for PCs short of RAM and page file; reports carry pc.ram_gb and pc.commit_free_gb. Stuck loads: - A load in one stage for two minutes sends a stuck-load report (every thread's stack and the log, error.type stall, load.stage, load.seconds) while the game goes on (crash protocol 6). - A load the player closes sends its timing with the stage it was in. Logs: the PanelTrace diagnostics and the neighborhood unlock override's observation lines are gone.
