Error When Visiting Cases (Lightning)

In what seems sproatic, our users are getting errors when visiting cases in Salesforce Lightning. We have two custom lightning components right now that a developer made for us, Case Merge, and seeing if anyone is also viewing the case (which is temporarily removed).

The error is the following - is there anything that can be done? This seems to come up semi-regularly.

Uncaught Component class instance initialization error [Definition does not exist on the client for descriptor:markup://support:compactFeedItemHeader]
Callback failed: serviceComponent://ui.chatter.components.aura.components.forceChatter.chatter.RecordFeedContainerController/ACTION$getCompactFeedModel

Have you ever found a solution for this? One of my users is hitting this error but only in Chrome, and I am trying to fix this for them.

Hey Jordan, I wish - these errors kind of come and go with Salesforce Lightning. We're finding that Google Chrome extensions aren't great with it either, so check that. Good luck!

Ok thanks Stephen will do, thanks for the quick response!
