PC Terraria switching worlds bug.

[YodaRocks3]

When I am in one world and try to exit and join another, (because I have two worlds, and one of them is full of farms), the game crashes and an error shows up, as seen in the image provided. Sometimes it doesn't happen though. I am confused. It only doesn't crash when I start a multiplayer world. My mods are:
WeaponOut v1.6.3
Fargo's Mutant Mod v1.2.6
AutoTrash v0.4
Brighter Torches v1.0.1
Shorter Respawn Time v0.2.5
Max Stack Plus Extra v1.0.2
Magic Storage v0.4.3.3
Infinity - Endless Items v19.0
Recipe Browser v0.7.2
Calamity Mod (No Calamity Music) v1.4.2.4
Calamity Mod Music v1.4.2.1
Alchemist NPC v8.4
Boss Checklist v0.2.1
VeinMiner v1.3.0.5

If you search something in recipe browser and dont delete it before switching worlds this error will appear
