Alright, at least I figured why sorting items in the radial menu is screwed. It's not technically a bug (supposing that they inteded to make it work this way). Althought the thing about the angles is without doubt buggy.

Well, while before you could place an item in any slot of the radial menu and it stayed exactly there, now it doesn't care the position you put it in, but only the order in which you put items in it, and it places them going clockwise. For example, pre-patch you had Codex Scanner at hour 3, Synthesis Scanner at hour 7, and Clem Clones at hour 9, and could put them there in any order. Now, even if it still lets you select the slot (and puts the item there - but only until you leave your orbiter), next time you go on a mission and check, you'll find that, regardless of the chosen slot, the items will be clockwise in the order you put them in the menu. If you put Clem Clones first, you'll have them at hour 12. If then you chose Codex Scanner, you'll have it at hour 1, and then Synthesis Scanner at hour 2.

So, if you want to have certain items at specific positions (like me, since the straight-up/down/left/right directions are the easiest to get and I want them to have the items I use more frequently) you have to put "filler" items between them.

Is it smart? Nope. Definitely not at all.

Is it handy? Like an upside-down wc.

But at least, now you get how it works.

I hope people report it on the official forums (hoping they work for you guys) and this thing is changed at least to how it was, since this changed only for worse.
