Considering the fact this bug has been around for a long time ... the factor of changing an ip address has no effect on this bug considering every single person gets this. the only way to avoid this is by opening your items every 10 or so battles. I have really good internet and have tested this on different operating systems / pc sets up / internet connections and still get it on all. I have also made a bug post about before! and Still hope this gets fixed.
Edit: If you want to test my theory on this go hunt with out hitting items for about hr or so then hit items I bet you freeze ;)
We were not able to replicate this bug, hencewhy there is no fix.
Me and wife can Replicate this multiple times over ( on different computers) just by doing this -> Edit: If you want to test my theory on this go hunt with out hitting items for about hr or so then hit items I bet you freeze ;) As well it has happen today 2x's just hunting for Xmas pokes
