Crash log here.

I added Reflection to my shield and things were going great.
But now when I block a Blaze's fireball, the game freezes for a few seconds and then crashes with a code -1.
I am unsure if this affects anything else or if it's a mod incompatibility, though it's a little inconvenient.

If there is no response soon, I'll close this issue.

Update: It also applies to creeper explosions, and strangely enough, being set on fire by lava.

What seems to be happening is that the ticking causes Neruina to kick me/the entity out, causing the null pointer exception because now there is no attacker. And then it crashes. I guess for now I'm going to disenchant my shield so that I don't crash.

hmm this is an interesting issue. What you described seems to be the problem. I'm going to test this on my end. Could you say what MC version you are on? Also, is the Reflection enchantment the one that is made inside our library or a custom one you made? Additionally, did this happen in the normal launcher or a dev environment?

Is this still an issue?

Hello?
