ha! i talked too soon.... while doing a sync just now, again i got the same thing, this time with only BTC core running, i guess i need to rescan o re-do the whole blockchain at some point soon.... that will need 1 week or so though... arghhh again invalid block.
this time was a bit weird, it started doing the sync, was a good point and only 369 blocks left

any tips to do a full rescan or complete blockchain sync again? of course i just ignored the block again and it worked again.
