[Flow] Get an 404 error after switching to "production"-context

[Mira]

Hey,

Everytime I work with my flow project, I develop and provide it to my visitors
in development-context.
Now I want to switch to production-context for my online version. For this I
edit my apache-config from SetEnv FLOW_CONTEXT Development to SetEnv
FLOW_CONTEXT Production.

After this I flushed all caches with this command:
FLOW_CONTEXT=Production ./flow flow:cache:flush

Now when I try to reach my site, I get an 404 error.
An axception is also thrown:

Uncaught exception #1303209195 in line 77 of
/var/www/flow3/timbo/Data/Temporary/Production/Cache/Code/Flow_Object_Classes/TYPO3_Flow_Mvc_Dispatcher.php:
No controller could be resolved which would match your request. Package key:
"Timbo", controller name: "Standard".

With "development"-context everything is working. Is it possible that flow looks
for my package in another director instead of Packages/Application/Timbo ?

Thanks,
Mira
