Cow tamriel 0 0 no longer works for me causing all times an instant CTD , this makes testing for me impossible ... ofc I didn't had this issue right befoure the patch ... anyonelse experiencing this?

Do you have any mods installed?

Of course just my wip mod , and befoure I could transport to and from issgard without problems now I CTD All times

So am I the only one?

Its: cow tamriel 0,0

You forgot the ,

ùI never use the comma , I can travel anywhere without , since when is needed?

Since when is it not? Ive always used the comma since Morrowind.

I can confirm that v1.526 you don't need the comma (I just tested it out of curiousity... I've always used the comma too). I haven't updated Skyrim yet, because of all the issues that keep popping up. So either they changed it in v1.6 or your plugin has somehow become corrupt or erroneous... which I've heard some version of the new update did (but I though they rolled it back).

I never use it.

I don't know about Tamriel but I still use 'Cow Falskaar 0 0' (Or whatever numbers) on a daily basis.

Can you cow into your own worldspace, or can you load into other things? (With Coc or loading a normal save?)

Yes can cow to my worldspace finely just not from other worldspaces to tamriel ....
