It names the cause and the plugin at fault, cites the log lines behind it, and offers a fix you can approve.

Survival crashed at 02:14 NoSuchMethodError in EssentialsX, 9 crashes in 40 minutesCrashing Fixed this way on 37+ servers: 37 Paper servers hit this after updating to 2.21.0; rolling back fixed 35 of them. AI diagnosisHigh confidence EssentialsX 2.21.0, installed by the 02:08 update, calls Player.getRespawnLocation(), which Paper 1.21.4 build 212 doesn't have. It throws the moment a player joins. Root cause: Plugin built for a newer Paper build Why we think so - The crash starts 6 minutes after EssentialsX moved from 2.20.1 to 2.21.0. (2 sources) - Every crash is a NoSuchMethodError inside EssentialsX's join handler. (1 source) - The same fix worked on this server on October 12. (1 source) Proposed fix Roll back to 2.20.1. 2.20.1 ran for 19 days on this Paper build without a crash. Roll back to 2.20.1 Runs as a tested change: a checkpoint snapshot first, 15 minutes of checks, automatic rollback if the server gets worse.

Evidence TrailEach claim opens to the log lines, metrics or timeline events it rests on. A fix you approveUpdate or quarantine the plugin, or roll its jar back, with a checkpoint and undo. ### A card within seconds The plugin reports crashes and hangs with the error signatures from the minutes before.

Every claim cites its evidence. When nothing supports an answer, it says so and tells you what to collect. - Cites every claim - Fleet data only as support - Not enough evidence is an answer ### Fixes that can be undone Update the plugin to a newer release, move its jar to quarantine at the next stop, or roll it back to the previous jar. Each runs as a Guarded Change: checkpoint first, 15 minutes of checks, rollback if health drops.
