The server freezes for some time and then crashes when making a specific trade with a gardening villager.
The trade is 6 emeralds to 2 glowberries if it's of any importance.
Also, it upgraded the villager's level either from apprentice to journeyman or journeyman to expert if that's the cause. I can't seem to find which.

I'm running the version 1.3.0 of the modpack with the following mods installed in addition:

• Carpet
• CarpetFixes
• Spark
• PingSpam
• MemoryLeakFix
  • NOTE: I updated DawnAPI from 3.3.1 to 3.3.2 to ensure compatibility.

Here is the crash report:
