I have no idea, all I know is that I never had the issue again since I stopped using GCM

Are you using admin commands? I didn't use them since first day and server runs fine (has around 10-20 players online)

Hi, I have already submitted this as a bug report, but I am also posting it here, so other server admins can find it. TLDR: If your server suddenly doesn't start and only wiping map helps, check map save for oversized tribe data file: https://imgur.com/a/7rja5Ca I have started a small community server (self hosted on my own hardware) and it went pretty good gameplay and performance wise, but the map got corrupted twice in a day.Server didn't crash, but the map files got corrupted and prevented a subsequent startup, either after restart or a natural crash.When this happened first time, I tried what I could to debug the issue, I reverted back to default settings, verified steam server files, reinstalled ark etc, nothing helped. I then blamed it on data corruption from single player data downloads (which were accidentally enabled on my server).So I wiped the map, fixed the config (to prevent data downloads) and restarted. Soon after, I wanted to change the rates a bit, so I restarted the server with rcon commands (SaveWorld, DoExit).After I changed the config (just some multiplier values), it failed to start again.This time, I was sure that it was not my fault (it was impossible to download corrupted dinos / items), so here I am submitting a bug report.I tinkered some more and found out that the map itself is not corrupted, as removing player and tribe files fixed the issue (arkprofile, arktribe and related files).I then noticed one file that stood out: https://imgur.com/a/7rja5CaYou can see an arktribe file that is 100x bigger than all other similar files. And sure enough, removing just this one file was enough to fix the issue - server started again.I am not sure how this file got created, I didn't execute almost no admin commands at all, just some quick gcm / flying to terminal to test if single player downloads are really disabled.Here are my server files - configs, logs, map data (including the corrupt file) and crash dumps: https://arkhungaming.hu/saved.zipThanks, hopefully this report helps resolve the problem
