Having spent a while messing about with the later versions of TPT, I realised that upon passing BOMB through portals, the blue portal just self-destructs. As awesome as it looks, I do think this issue needs to be corrected.
@lolzy(View Post) This glitch is great because portal makes the element normal again. Like firework exploded then sucks into PRTI and comes out from PRTO to be ready to be exploded again. I want to keep this glitch.
