First of all: Many Thanks for the supporters, working during their free time to provide /e/OS builds! 
When i read this, i am wondering:
For now the team is working on resolving these issues in the upgrade build
Actually i do NOT need an UPGRADE build ! I would be even glad to also start from zero and wipe my S8 but have a fresh build! Having this very outdated version of security patches is giving me a headache. So wouldn’t it be an option to make at least the users happy that start from scratch now?
I compiled LineageOS builds by myself in history and in my opinion it is 2 steps:
- Having a build that works from scratch and
- having an upgrade path.
So when i read there is severe bug with the upgrade build, i do assume the package as such is already done. It would be also very natural that an upgrade from P to S, so jumping over Q / R will cause some headaches. So why not giving users an option: Wait for the OTA or take what we have so far?
To get this right: I have also given money to murena.io (means to me, i am also willing to support). And I would not expect much, but it seems i have taken the wrong decision.
