After upgrading to the newest EAP (as of October 7), 143.90, RubyMine no longer recognizes any methods, classes, etc. from Rails or other gems (see screenshots).
Additionally, It no longer knows what the "Application" is in the File panel. When you click on "Application" (again, in a screenshot), it changes the File view to "Project" from "Rails", rather than opening the ApplicationController as it did in previous versions, which you could also expand the "Application" icon in the File view and see the relevant helper and the like.
I've tried with a few different projects (all the same) and I've switched SDKs as well (2.2.2 to 2.2.3 and back). No luck.
I've upgraded to the new EAP within RM but then downloaded the .dmg and tried a fresh install (wiped all caches, preferences, etc.). Also, no luck.
Wondering if anyone else has seen this with the new EAP?
EDIT: cannot run a server from within RM as well. Tells me that Puma is undefined in the Gemfile. But I can confirm it is not only in the Gemfile, but also in the list of gems installed in the preferences pane.
EDIT II: Attached log file to the original post
