Molotov Cocktails corrupting chunks

[Ivorforce]

Hey there Ivor, I'm absolutely in love with your Psychedelicraft mod, but I unfortunately had to remove it from my server. There is an issue with zombies using molotov cocktails on players and creating corrupted chunks. I'd greatly appreciate some type of fix or suggestion as to why this is happening!
