This happens after sync is completed and it starts to plot.
Going to try to wipe the summary since the error seems to be related to it.
This looks the same as Alpha 0.3.0 solution subscription crashed - summary was corrupted
Yes, it does look like a similar error, but mine is at the initial plotting stage.
You wiped before moving to 3.1?
I wiped the summary. That was it.
I believe the summary is related to the plot which means the plot may be corrupted and need a full node/farmer wipe.
@ozgun can you comment to verify or add any insights?
