Details of the issue:

Made a customized modpack with FTB Light as the base. It worked perfectly for about 24 hours of gameplay. Now it crashes within a couple minutes of game time. Couldn't find any posts with this exception. I appreciate any help.​

I added Ancient Warfare, Ars Magica, Tinkers Construct, and Decocraft.
I just don't understand why it worked for days and then started crashing.

does it crash if you start a new world?

No. I tested a new world and it ran without crashing.

Then something in your current word got corrupted. I have no idea what com.mia.props.BlockProps refers to as I never used any of the added mods.

It wants to do something with the air block and entity rendering if I read it correctly but I have no idea how to solve it or what mod causes it. sorry.

Thanks for your input.

Solved. It was Decocraft. I had to deactivate it which is disappointing because I really wanted that mod.
lenscas's post made me realize that com.mia.props.BlockProps referred to something in a mod (I had assumed that it was something from minecraft). I searched the mod folders until I found a reference to that.
