Random Crashes

So I've been getting a lot of random crashes today, all with the same error but different numbers at the end. This happens when I go out of shadow clone, but other times it just does it randomly. Here's the error I get:
Is anyone else having this issue?

 

Yes actually me as well
Here

 

K, good to know is it's not just me :P

 

But yours is serializer 40 and mine is serializer 16

 

I've gotten like 20 different serializers, including 16.

 

What's a serializer? I'll look into your problem

 

Idk, I'm a turtle expert not a computer expert :P

 

I think mine has always been serializer 16

________________________________

It seems to occur whenever I right click directly on anything with my bow (it seems to be only on my archer)

 

Same with my dagger, that's probably why I crash when going out of shadow clone.

 

The questions to ask: what version, any mods, anything else running?

 

I have soundcloud running in the bg. That's all.

 

All thats open in bg is this forums page. Version 1.9.4 and 1.9.2 both have the same outcome

 

Why not play in 1.8.9?

________________________________

Tested my Archer on 1.9.4. I've done spells, went on the horse, right clicked on NPCs, no crashes.

 

In 1.9? First of all, how the frick are you riding a horse in 1.9?
It's almost always happened to me when I use a re-skin class.
It almost always crashes when I shoot anything with hunter, and it ALWAYS happens when you use shadow clone.
But then I have random crashes such as when I'm walking somewhere with my mage or archer.

 

Like I said, just play in 1.8.9.

 

I find it impossible to install optifine on both 1.8 and 1.9, so I need to delete and re-install optifine each time I switch versions, and I use 1.9 for my single player worlds.
Not playing with optifine is out of the question, I get 40 FPS AT MAX.

If anyone has a quick solution for this, lemme know. I bet there is and I'm just stupid.

 

Hmmm.. Well I would just have one of the versions with no optifine really. 40fps isnt bad if u wanna play a game. Remember this is Minecraft we're talking about.

 

40 FPS at max.
Usually about 20, depending on how many mobs/blocks in my render distance.

I'm getting a new PC Soon (TM), so that'll help.

 

My old computer capped at 54 and usually hovered around 17 and I didn't realize how bad it was until I got my new computer and have a 100% contant 60.

 

Ah... Shadow Clone causes WC to crash when using 1.9+.

I've heard of bows causing crashes in 1.9.4.

Welcome to the club, I've hit highs of 100 as the game loaded me up in the spawn area...

My constant, depending on the time of day, and on WC location, can be anywhere from 30 (Mid-morning, Llevigar Plains), to 5 (Night, Canyon of the Lost, near Thanos).
