I think the v3 just removed all of the shows on my collection on Trakt and replaced it with only the shows/movies I have on my laptop
I wasn't expecting this behavior from the option to 'remove items from collection when deleted from Kodi', I thought the addon will only work with the items that got added to Kodi after installing the addon, this way it doesn't accidentally wipe my collection of 8000 episodes just because i don't carry all of them on my laptop at once

just a thought

Thanks again to @Razee for the awesome work he did on this, at least the addon works so much better than the previous one

EDIT: or is the 'sync' option that caused this? so i can know which to disable

It is the "Remove deleted XXXX from trakt collection", it's disabled by default for new installs.
