Hi ! Sorry if this is the wrong place to post : i read the FAQ about reporting a crash, but it didn't mention a specific place to post.
So, i'm playing modded minecraft for years. I had a lot of crashes but it usually happens on the firsts launches (missing dependencies, wrong mod version, etc...). I never had to post here since minecraft crash-reports are fairly usefull to find out what's wrong, and google helps too.
So, i come to you guys for help after a lot of researches.
The crash occured on a dedicated server running :
Theses files were provided by the server, i did not put them here myself.
The server was working fine, my friends and i played a few hours without issues.
The next morning i realized the server crashed at 7AM when nobody was online.
I rebooted the server, everything worked fine, we played all night.
Next morning, the server crashed again. I rebooted, and kept playing.
This went on for a week, before weird stuff started happening.
First, a few fruits added by Pam's HarvestCraft were corrupted and changed into fluids from Thermal Expansion. Then the fluid changed for wodden slabs from forestry. Finally, most of the modded blocks simply disappeared, making us start a new map. Unfortunately, i didn't kept a copy of this crash report.
So here we are, new map. We deleted most of the alpha version mods to avoid any new crash. The server started without problems, we played for a few hours.
This morning, i check the server : He crashed during the night. Here are the crash reports from minecraft and forge. Nothing seems to indicate that a mod is causing the crash. Help would be greatly appreciated.

So after a lot more researches, it probably has nothing to do with mods. It seems the server tries to "auto-save" the world and encounter an exception with a method and a class (https://bugs.mojang.com/browse/MC-104592).
So i sent a message to my server provider, but if there is someone out there who knows what's happening with this crash report, you are welcome.
