Asset blocks

I am finding the asset block tool one of the most annoying and frustrating tools ever to be introduced into this game.
It seems as though the more assets a route has enabled that fall into the catagory of being able to be used in an asset block the more likely you can get out your party hats and balloons and celebrate constant sbhh.
It hates 3DTrains scenery pack. Sometimes they work, sometimes they don't and crash. Also noticing is the density is constantly altering to incorrect values. Like, I will have an asset that populates and the size it set to 1000 or 500 automatically, then I will pick another asset from the drop down list and its blank, density set to 2 or some other odd number. Changing it will either make the items appear, crash, or appear as ugly artifacts instead if I don't pick the right density.
One route of mine just completely crashes as soon as I plop down the asset block and double click it to bring up the properties flyout.
For me, this tools flakeyness just negates a reason to even bother using it.
Anyone else having such issues?
