---1: What did you do?

I attempted to build a space platform using legendary platform, and also attempted to build it with any other quality of platforming

---2:What happened?

The ghost tiles remailed unplaced, unless I put normal quality platforming into the hub

---3:What did you expect to happen instead? It might be obvious to you, but do it anyway!

I expected that the platforming would be placed, although losing its quality information. My friends are planning out a mega base (hence why this is in sandbox when i found the bug, i was planning blueprints) and while we dont see the need for making quality platform explicitly we will be making quality copper and steel, and we would like to be able to make platform from the main supply. While we can make a non-quality production line, it would be simpler to keep everything the same.

---4:Does it happen always, once, or sometimes?

Always - I was able to replicate it across two totally different saves (1 modded, 1 vanilla) and across multiple platforms (Including platforms with a high quality Hub)

--5: Steps to Replicate (Vanilla)

1) Launch brand new sandbox map, with Quality, Elevavated rails, and Space Age enabled. Do not modify any world gen settings
2) Give all Techs, set to day, enable cheat mode, no starter items
3) Using cheat mode, place a solar grid and a rocket silo. Fill silo with parts to launch rocket, load starter pack, and launch
3a) Creating new platform via the /editor also leads to the same ending behavior
4) Once starter pack has assembled, switch to the platform, then insert multiple stacks of quality platform into the hub
5) Place a large ghost block of platforming to be built. The Hub will use the starting 10 platform, and then will stop placing anymore

--6: Notes

I couldn't find a previous thread about this on the forum, and only found a single reddit post (https://www.reddit.com/r/factorio/comme ... ations_is/) in which the poster also ran into the issue. If there is an existng thread, please link it to me.

Thanks for the report however this is working correctly. Platforms can only be built with normal quality items and placing ghosts only ever makes normal quality ghosts.

Quality platform items only exist for recipes.

Interesting. I would have expected that the platforming could be used, even if it lost the quality info. Is the rational behind that the same for why the rocket silo wont take quaility components?

I hope this can be changed in the future as one should expect at least similar functionality from a higher quality component.

Quality Tiles provide no additional Stat benefit. Previous Bug Reports have been filed for accidentally placing “valuable” Quality Concrete, which reverts to Normal Concrete as a Tile since the Quality level is not stored… The solution is to not allow Quality Tiles anywhere.

That is not really a good solution.
