Game not properly loading ALL game assets during save loading process

This results in various issues that SEEM to be all different, and APPEAR to the user to either be a mod issue or a graphical bug here or there- but it's actually just Space Engineers not having finished loading ALL the game assets (including workshop items) at the time of request.

As this sounds vague, I'll list a few (modded and vanilla) examples.

First, players may notice that when placing a block (for example, a Basic Assembler) that it only shows the Placement outline, but not the Hologram of the block itself- and that when placed, the Build Progress block (wireframe?) doesn't even render- only for it to show up a minute later as if nothing happened, and that specific block then loads and every instance of it performs perfectly fine.

Second, a modded example. When loading a world with a Music Addition mod of any kind, and the added song(s) are queued up on the Jukebox, most of them will fail to load or play anything at all. If the song is re-requested after a period of time, it MAY play perfectly fine, or still not play, and require another song to play fine first before the song can be re-requested. (Using the example of a modded song being added because of the relatively large filesize per song, meaning it's more obvious if the asset has been loaded yet or not.)

Note that in both examples, it self-resolves eventually (the latter example self resolving roughly 75% of the time, otherwise requiring a save reload).

I BELIEVE this is due to the game only loading the assets currently in the world, not ALL of the game assets including Workshop items. If you guys could test different asset loading methods or a way to make sure ALL registered game assets are loaded during the loading process, I can only assume that these and similar bugs will go away.
