I did update to 1.1.3.8c but the wallet never starts. It's been sitting for more than two and a half hours at "Loading block index".
Id did the wallet cleanup process after I installed the latest.
Last line in debug.log is: 2018-07-04 10:58:09 LoadBlockIndexGuts 1530701889.000000 2018-07-04 12:37:26
Should I just revert to 1.1.3.7 for now?
The wallet seems to consume up to about 1,7GB of memory before going back down to about 1GB, and just going in circles with that.
If you had it running during the superblock bug, then the index can be corrupted.
if you delete the chainstate and blocks folders in your data dir, let it re-build them. this will take care of it.
If it's your main wallet, make sure to re-start the client after it has synced so podcupdates work again.
