I figured it out. I tried to jump directly to 13 from 11.Flashed it manually with the fastboot utility from Google platform tools, but you need to first extract the payload. Fastboot enhance should make this process even easier. I suspect the issue is with virtual partitions, possibly a mismatch between the number of extracted images and the number of partitions available to flash. If you simply flash the ones that match the extracted images you'll be fine -- that is likely the default if you ignore the warning.
What i did is firstly updated with ota (incremental 400ish mb), then unlocked bootloader. After that flashed 4gb oos 12 ota from the updater. After that just flashed the payload with fastboot enhance. Now i got l1 on oos 13
