Hey there I just found your mod and wanted to put it in my modpack. As I was testing I created a Nether Portal went in and out of it really awesome, then I created a Twilight Forest Portal. went in and out then back in then out when I went in again it was almost an infinite amount of portals and froze my game up. Looked into my logs and got this https://pastebin.com/5CPJ64L3

I know I have a lot of mods, but I am hoping you can help with this. Thanks very much!
