Custom Modpack Crash

[Rei_Senpai]

Hello, I'm new to the forums, and I don't know where exactly to post this. I have a custom modpack that uses the FTB client (It is similar to the Direwolf20 pack, but with a few changes). After some work, I managed to get all the id's to not have conflicts (using the id resolving mod). But from time to time, it decides to crash randomly, and I get this error. I'm not sure what I can do to fix this, any help would be appreciated.

Try removing Ars Magica and see if it still happens. It seems it is having problems.

I'm not very good at these kinds of things, but I can very easily say that there may be some block that the Ars Magica particles do not like. Range check is where I might have gotten that. But, don't take my word for it. Just remove Ars Magica, or any block that might be emitting particle effects from AM.

Ok then, is there a possible way of configuring Ars Magica to work with my modpack? I would really like to use this in my modpack.

I have removed Ars Magica and I'm still getting random crashes, here is a piece of the long crash log.

What version of Ars Magica are you using, if I may ask?

Edit: Scratch that, didn't notice you removed it.

You are using a block ID over the limit (3999).Try setting it to 917 or so(It should be free)...
