      A google search for "spigot server bug AdvancementDataPlayer.e" led me to a site for PaperMC/Paper. It was exactly what I am experiencing:

      https://github.com/PaperMC/Paper/issues/3019

      I freely admit I do not understand all the various Minecraft server versions.

      I am very new at dealing with a Minecraft server. I rented a server, they suggested I use spigot rather than vanilla, so I did.

      We started on 1.13; now we're up to "Spigot latest": [23:43:52] [Server thread/INFO]: This server is running CraftBukkit version git-Spigot-56f8471-3e3818b (MC: 1.14.4) (Implementing API version 1.14.4-R0.1-SNAPSHOT)

      We get a crash that seems to occur when one of us logs onto the server. Not every time but we usually get it sometime during every play session. It's been happening for months.

      It appears to be an infinite recursion:

      [23:43:32] [Server thread/ERROR]: Encountered an unexpected exceptionjava.lang.StackOverflowError: null at java.util.HashMap.hash(HashMap.java:339) ~[?:1.8.0_191] at java.util.LinkedHashMap.get(LinkedHashMap.java:440) ~[?:1.8.0_191] at net.minecraft.server.v1_14_R1.AdvancementDataPlayer.getProgress(AdvancementDataPlayer.java:417) ~[Spigot_Latest_1.14.4.jar:git-Spigot-56f8471-3e3818b]

      and this last message is repeated dozens and dozens of times.

      If this is the right place to report this bug, I will be glad to supply the log files/stack trace/datapack list and whatever else you'd require. If not, would someone be kind enough to direct me to the correct site? Thank you and I apologize if I've caused any trouble with a bug report that is not a complete bug report.
