if you read the stacktrace you would see that the issue is 100% an issue with timings, the OP has the RB 1.8.9 SF and has issues running /sponge timings report, i am running Pixelmon on SF 1666 (ie latest) and can run /sponge timings commands as much as i like with 0 CMEs. 99.9% of our CME causing code is gone so this is definitely not Pixelmon
