Oxygen Sealers cause crash after update from 1.4.18 to 1.5.5

[Aedict]

Hello, I just updated from 1.4.18 to 1.5.5. Prior to updating I removed all ex astris and modular system blocks. Now oxygen sealers from galacticraft always crash my game. I tested them on a newly created creative word and as soon as I place the sealer and it attempts to seal, it crashes, so it is not particular to anything in my single player base. Below is a copy of the crash log. Any help would be appreciated.

Chisel: Errors like "[FML]: Unable to lookup ..." are NOT the cause of this crash. You can safely ignore these errors. And update forge while you're at it.
EnderIO: Found the following problem(s) with your installation:
* The RF API that is being used (1.7.10R1.0.13 from ) differes from that that is reported as being loaded (1.7.10R1.0.12 from RouterReborn-1.7.10-1.2.0.35-universal.jar).
It is a supported version, but that difference may lead to problems.
This may have caused the error. Try reproducing the crash WITHOUT this/these mod(s) before reporting it.
