Install a component (I've tried ACL Manager and Admin Tools)
Go to component in backend
You see the component
You get a 404 Component not found.
Clearing the admin cache fixes this issue, but surely it should not be happening.
No Code Attached Yet
I cannot reproduce sorry - I have been installing extensions into Joomla 3.7.0 all day :)
This appears to only be on project properties. Closing this and going to Rochen.

Well, this might be a bug in core. If the install/update routine isn't clearing the
_system cache group this issue can manifest itself. I'm not going to reopen it just yet, but if someone wants to do a quick investigation, that'd be what you need to check.
Well with cache disabled clearly. But the project properties for the most part all have cache enabled so the part about needing a cache clear might be valid.
Well, I did go ahead and do that scan and https://github.com/joomla/joomla-cms/search?utf8=%E2%9C%93&q=_system&type= doesn't show that cache group being cleared. So there is a legit bug with cache enabled at least.
When disabled is another story.
FWIW I've basically seen this same thing with the caching in reverse almost. With cache enabled, disable a component. The component's still accessible.
