These are bugs, some already known for a longer time, some only to enjoy after 1.05.

Most of them funny things (like the Monty Python silly kind of walk), some only "disturbing" in a visual way, like:

- after bombarding a bandit camp (or any other gathering of meanies): you'll have to do some cleaning up, colliding with all kinds of body parts that hover in the air

- by walking through a crowd (hopefully a friendly one): reacting fast to those folks that are popping out of nowhere, ca. 10 m radius. Especially nice when one of them "up-poppers" carries a bow and is aiming at you.

There are, sadly, other things that are maybe more of the bothering kind.
Take these mutagens, for example:

while playing you gather heaps of the stuff, most of them with lesser power. Would it really be some kind of rocket science to implement the possibility for the player to combine a few lesser mutagens and thus get one really nice mutagen that will bolster up Geralt.
As it is (and if I did not miss a vital thing here) Geralt is carriyng some 30 or more mutagens that never will be used.

The game as is - still a lot of fun. Does not mean that it could be better (like a whole f...ing lot of great fun).

EDIT: sorry for the typo in the header - got to decrumble my keyboard, it seems :)

This can be done. Two Lesser Mutagens make One Mutagen; Two Mutagens make One Greater Mutagen. In Alchemy tab. Named Mutagens (Basilisk, Nekker, Wraith etc. can't, unfortunately). Mostly, they're useful for selling.

It's not only a hovering debris, is all kinds of objects that start to levitate after 1.05... Dead bodies included (see pic). IMHO game engine have problems with calculating correct "ground" level and therefore object - ground colisions, especially when dealing with sloped or uneven surfaces... While it's raher hilarious than game breakig (although I was killed at least once by bunch of common drowners because after seeing how game is tossing them around after being hit I was laughing too hard to properly dodge...) it will be nice if CDPR will fix this.

The named one are required for Decotions,so keep a sample of each named mutagen,the rest you can sell..
Atm I have 2 Greater Red and 2 Greater Green,and they are more then enough for my build
keep in mind that the alchemy talent Synergy will pimp your mutagent bonus up to a +50% at 5/5

Please: care to explain?

I can craft all sorts of things, mutagens however are not one of those (especially "combining" two or more lesser into one ....).

Any help would be very much welcome, thanks!

First of all, there is a bug that prevents you creating a mutagen if you already have one of the same, so if you want to craft a blue mutagen, drop any other blue mutagens that you have on the ground temporarily. Once you have done that, and you have sufficient lesser blue mutagens, just go into the alchemy tab, as shown in the attached image. Any green items can be crafted.

Thank you - waiting for this to be fixed, then.
