Hi i made a new Engram and used the option in the PrimalGameData file to remap and override one of the orginal engrams. And it works fine.
BUT. When i get ingame and try to place the new engram it show the placement dummy. But i can’t place the item it never spawn?
If i don’t use the remap option in the PrimalGameData and make it as a new engram it all works?
Anyone that can tell me how that works?
Is your engram pointing back to the default structure, is it pointing to a new item that you’re replacing something with… more information is needed here.

WM you are really a good helper here on the forum, thx for that 
Im trying to make a new type of torch as you may have guessed from the BP you helped me with (that im still working on)
That only turn on and off at day and night if it have a specific item in the inventory.
So when the item is done i like to replace it with one of the old items.
Right now im just testing it on the StandingTorch
In the PrimalGameData i have in my mod folder i go under Remap Engrams and add a new element.
Under From Class add the orginal EngramEntry_StandingTorch and in To Class i add my new Torch.
It all show up right ingame and replace the old one and i can craft it and all. But when i try to place it i get the green dummy mesh but can’t place it. Its i´like the placement on the item is missing.
But the “Funny” part is that if i remove it from the Remap Engrams and add it under the Additional Engram Blueprint Classes it all works fine :)?
Hahaha got it to work 
Found out that i simply needed to add the Torch to the Additional Structures to Place longer down also.
So many hours last night for that little ting.
But sometimes all that is needed is a new day and some fresh eyes
So now i can get back to the Script and try to get that to work.
That was to be the next suggestion, I was firstly working towards ensuring your structure was consuming correctly.
