So the Intravenous Needletip replaces the syringe for drugs like morphine and other injectable drug, but i can't inject serums.


Can someone correct this?
@Xhuis just a heads up.
When did you last update? This was patched last month in #25577.
I've confirmed it just now on most recent master available. Code looks good at first glance, so I couldn't pinpoint the problem.
What I've spotted:
I've noticed that if you examine the serum and then activate it it will work.
Eat menu shows message as above. [A]ctivate doesnt show serum on the list. Even in [e]xamine it looked like it wouldn't work, but it worked.
Forgot to post the build

@nexusmrsep I have noticed this before with disinfectant. i have a 'small bottle of disinfectant (5)' when i press 'a' its not in the list. but if i go to it with 'i
@woutershep You can also "E" and select the disinfectant, but it just doesn't appear in the "a"ctive list
I need someone to confirm this.
To me it looks like line 38 in data\json\items\comestibles\mutagen.json should be "tools_needed": "syringe" and NOT _"tool": "syringe"_.

Why? Well, take a look at \src\iuse_actor.cpp line 544 f.

I've tested the change with my build and it worked fine:
mutagen - new.json (new file)
mutagen - old.json (original file)
mutagen.json.zip
Just change the name back to mutagen.json.
At least this should fix the mutagen bug.
@nexusmrsep I have noticed this before with disinfectant. i have a 'small bottle of disinfectant (5)' when i press 'a' its not in the list. but if i go to it with 'i' and then 'a activate' it does activate and i can select a limb. maybe its related to beeing in a container?
@Heaper327
Would you mind testing the disinfectant issue with the current build.
Seems to work fine (all of the above work fine / 'a', 'E' and inventory -> activation/use).
