Gorou, it's an on/off type of thing.
sometimes it stacks for me, other times it doesnt.
THERE is something weird about Decal/plugins since the patch and unfortunately i did some windows updates just afterwards.
BUT besides the original no detection of moarsmuck, i've had the stacking issue pop up and now something weird with SSSort so i had to resort to using SortIt! (more sort options with sortit, but then i'm only usually sorting salvage 99.98 and 44/100 % of the time so not critical, but sssort seemed to in earlier installations have less dual logging issues).
anyway recently SSort acted up, go to sort salvage and get message select pack to sort, and i've got main or a side pack highlighted. oh well reselect and same messsage, so i de-installed and went back to sortit
these are the 3 werid issues I've seen since decal3 alpha7 and patch. not sure if related underlying issue with AC, plugin(s), decal or system. best of luck hope this doesn't totally confuse the issue.
