[0.11.8] "Green coral" is not affected by poison

[JackGruff]

I have a suspicion that Green coral was meant to be non-collideble like its smaller variants, hence this oversight. But if it is to remain collideble, please make it affected by poison. It's a pain in some regions.

Thanks for the notice, it is fixed for 0.11.9 now.
