World comp tile seam will not take sculpting etc

I have uploaded video as seen to illustrate that I can’t sculpt ( or anything else) atm, on one of my ‘tiles’ in my world comp project.

OK I can’t upload more than 5mb which is kinda odd imho, but anyway so I had to put it on google drive:

Earlier I tried to recover placed meshes that somehow had lost their positions ( coudn’t find them), so loaded a different tile from a saves DIR in project , and now one of my tiles, NewMap2 isn’t able to scultp or anything else, over the ‘seam’ of it and the other tile next to it or on the other side from it.

I can sculpt on either side, but the seam remains unedited, unsculpted–how do I fix this mess ?:wink:

TY

OK, I backed up project , and renamed the newmap2old and copied in newmap2 from my backed up 4.21 project than GOD I didn’t delte it ( backed up on ext.WD hd), and that fixed that right up major WHEW, too much work to lose.

I still have a VERY mixed looking wc window, when I get a second I’ll paste a pic.

OK, I backed up project , and renamed the newmap2old and copied in newmap2 from my backed up 4.21 project thankfully I hadn’t deleted ( backed up on ext.WD hd), and that fixed thes seaming issue too much work to lose.

I still have a VERY ODD looking wc window, when I get a second I’ll paste a pic, and in its current form its completely unusable , and no changes I make resolve it , though removing some lighting, bp sky sphere maybe fog, post processsing does get rid of some of the ‘colors’ that overlay the wc window area and are not supposed to be there.

That is the not the main issue though, as I have 4 distinct tiles, and hovering over each one, shows the same ‘newmap’, which I’ve never seen happn before, thus I can only click on each one separately on initial load of project,after that I can’t, and furthermore, once it messes up ( nothing I"ve done ), I get this odd rectangular area saying newmap inside of it- which again I’ve never in the 2 or so years I’ve been using ue4 - is it possibly the result of using 4.22 too soon ?

Anyway here is the video verifications of what I"m seeing:
