Crash on entering Nether

[roppenheim]

Sorry if I'm doing this wrong; I got a null pointer exception on my SSP world upon entering the Nether, and it now crashes every time I re-enter. The crash report went as follows:
crash-2018-05-30_22.24.01-client.txt
And here's the latest log from the logs folder:
latest.log
Sorry if this isn't anything to do with StellarAPI, it just mentioned it quite a few times. I tried disabling the mod's GUI elements in the config to no avail.

Oops.

Try the latest Stellar API, 1.12.2-0.4.2.9.

It works! Thanks so much, I really missed Photoptics and Stellar Sky.
