[Gegy]

Do you remember in what file this occurred?

[Runemoro]

No, I don't. This wasn't a Minecraft class though.

[Gegy]

This seems to be related to the Procyon update. It seems to call visitInvocationExpression with comparison expressions like fcmpl(Math.abs(arg2.c), 22.5f). Enigma currently expects a MemberReference attached. Not sure if Enigma's assumption there is wrong or if it's an issue with Procyon.

[Runemoro]

This was happening before the procyon update.

[Gegy]

Interesting. Maybe a different issue before -- but the Procyon update has definitely caused this NPE to come up more than before.

[NebelNidas]

Is this still relevant? I've used Enigma a fair bit over the past year or so, and I can't recall seeing this particular error at least once

[modmuss50]

Most likely is still an issue as itsprocyon specific. I expect (and hope) you have been using CFR though.
