Alright, there are no crashes in my SSP world, and all my mods are working somewhat fine. However, whenever I either try to place a portal with my poral gun, set any liquid down, or try to make obsidian with water and lava, it doesn't exactly work. In order to make anything work properly, I have to quit then re-load my world, or right click the block that is supposed to be affected. Is there any kind of fix for this? I'll provide any information requested.
