What were you doing when the issue happened?

Mining ore blocks from Modular Machines

What did you expect to happen?

What happened instead?

Non-fatal exception pointing towards Bagginses
The exception does not occur when mining blocks from Immersive Engineering, or Actually Additions.

Crashlog on pastebin/gist

Not a crash, but exception report here inc. full mod list: http://pastebin.com/7TYjaGe2

edit: Sometimes fatal! Just moments after posting this, I returned to mining and the server crashed; client did not.

eddit: Crash may be dynmap related. Ignore it if it doesn't look like yours :-)

Forge and Minecraft version?

Forge 2122
MC 1.10.2
Bagginses 3.0.4g
Modular Machines 1.7.0.169

Any other known modifications to Minecraft/Forge itself that are known to cause issues?

Any other info which might help.

Hmm they both look to be the same cause. Something is modifying the drop list while I'm doing the same thing. I'll contact the dev and see what I can work out :)

Coolio.

In case it pops up, Other than a "Void Charm" from Cyclic, all other items are vanilla so there's nothing on me that should affect item drops.
