✅ | Crash with fancy menu

[tropic sentinel]

I think my game crashed due to fancymenu

I’m checking if this is a known FancyMenu crash first, then I’ll ask for the right log if I need more details 🧩📄

I got the crash file, now I’m reading it to see what actually blew up 🔎💥 If it’s a known FancyMenu thing, I’ll point that out; otherwise I’ll ask for the full latest.log.

I found the important bit: the crash is a ConcurrentModificationException, and FancyMenu is only in the renderer hook where it happened 🧠🛠️ The stack also points at valkyrienskies and Connector, so I’m checking whether there’s anything known before I tell you what to test next.

Heyy, I checked the crash report 📄🔎

This doesn’t look like a clean “FancyMenu is broken” crash. The actual error is a ConcurrentModificationException, and the stack trace also involves valkyrienskies plus Sinytra Connector. FancyMenu shows up in the renderer hook where the crash happened, but it doesn’t look like the root cause by itself.

What I’d like next:

• Please send logs/latest.log from your instance, not the crash report
• Tell me your Minecraft version, loader version, and FancyMenu version
• If you want to test fast, try launching with Connector + Valkyrien Skies removed first

If you send the latest.log, I can take a much better look and narrow it down more precisely 🛠️🙂

Latest.log

[ocean shell]

Nice, I’ve got the latest.log now , I’m checking what FancyMenu was doing right before the crash 📄🕵️‍♀️

Aha, I found a real stack trace area in the log , digging into the exact mod chain now 🧩⚠️ This should tell me whether it’s FancyMenu, Connector, or another mod causing the mess.

Thanks! I looked through the latest.log 📄🔍

What I’m seeing:

• FancyMenu loads normally
• I don’t see a direct FancyMenu exception in this log
• The crash report you sent earlier points to a ConcurrentModificationException, and the stack includes valkyrienskies plus Sinytra Connector
• Your log also shows the instance being “tainted” by mods modifying Embeddium internals, especially Oculus / PictureMode / Valkyrien Skies ⚠️

So this looks much more like a mod conflict / Connector issue than FancyMenu by itself.

Best next test:

• Try removing Sinytra Connector first
• Then try removing Valkyrien Skies
• If it still crashes, test with only FancyMenu + its dependencies and see if it still happens

If you can, send me:

• your Minecraft version
• loader version
• FancyMenu version
• and the fresh latest.log from a test where it crashes again

That’ll make it way easier to pin down what’s actually causing it 🙂
