Hello, thank you for reporting these bugs.
Please correct me if i did not understand you well.
1- the 0.2/m is not a bug, Scrapping gives you 1 Material per 5 minutes, and the MPM (Material Per Minute) show you how many Materials you are producing per minute, hence 1 material per 5 minutes = 0.2 Material per minute, and same logic for all productions methods.
2- Casting is working properly under the hood, the issue is that its energy and production texts are not updating accordingly.
3- as for the long weird numbers, it is a minor issue, and a simple fix
These bugs does not affect gameplay, so the fix will be implemented in the next patch :)
Thank you for sparing some of your time to report these bugs :D.
