Pixelmon Mod

That is, in fact, my question. I am a mod on a server, and we are going to update from Pixelmon 3.3.3 to 3.4. I know in the past we had an issue going from 3.0.4 to 3.3.3, with new block IDs for everything.

Is that the case from 3.3.3 to 3.4, or was the block ID issue just because we were changing MC versions as well (from 1.6.4 to 1.7.10)? (In this case, we're staying with 1.7.10 for the time being.)

Thanks in advance for the help, and pretty soon we'll have our server up and running!

yes, the ID thing was cos of the change in ID systems between 1.6 and 1.7+, there should be no issues going from 3.3.3 (which was a beta iirc) to 3.4.0
