yes, there still are memory issues, if you enter battles frequently iv found that if playing mostly auto battles ...you should be fine for about 2-3 hours longer ( on a 6-7 hours playing session...), im talking about an 80-90 age character ( your character...)
very sad to see this this game has had a funny history with this issue, one patch issue gets fixed the next its popping up again , im TELLING YOU THE DAMN SCENES ARE the problem, in the past when there were randomly generated and not terrain bound scenes the memory issues were mostly kept at minimum...
