F2FS Data Corruption (Major bug)



Hey,
I have a Nexus 7 2012 32GB. It was previously running pretty slow but then I installed SlimKat with F2FS and it started running fine again and I'm very happy with it. Today and earlier this week, I tried installing Android 5.1.1 since I like the Lolipop UI but I was met with a major problem.. I tried the latest nightly of CyanogenMod 12.1, Dirty Unicorns 9.7 (and 9.8) and Blisspop and their problem is that after one boot, the /data partition got corrupted.. I tried repairing it but got ERR=255 and the only way to repair it was to change /data to ext4 and then format to f2fs back again. All four ROMs are confirmed to work with F2FS... I have reverted back to SlimKat 4.4.4 with a backup since it's the only ROM that doesn't corrupt my /data partition. The device doesn't boot when the data partition is damaged and the recovery sometimes crashes (I use TWRP 2.8.7.0). Is there a fix to this or will it be fixed in the future? I'd be happy to provide any logs needed. I use Opengapps pico altough I don't think that really matters. F2FS makes my device much faster but the corruption problem is too major for me..

Thanks,
Aurora
