Message order is not always correct

Sometimes, the order the messages come in is wrong.

Real example after drinking 1 mutagen:
“You gain a mutation called Herbivore!
You gain a mutation called Leg Tentacles!
You gain a mutation called Poison Resistant!
Oops. You've must blacked out for a minute or so.
You drink your mutagen.
You wake up.”
This is from the broad sidebar, so this means: normally, new messages appear at the bottom. But this log looks a bit messed up. According to the log, you get the mutations before you drinke the mutagen, and you drink it while you are passed out … lol

It seems to me the message order gets wrong always if multiple messages go into the log at the same time, I am not sure exatly.

Oh, and I know C:DDA has this bug for a very long time already. Still in master.

Reproduce the reported scenario of drinking one mutagen and inspect the broad sidebar message log. Trace how simultaneous messages are added and determine why their displayed order differs from the gameplay order. Done means the mutation, blackout, drinking, and waking messages consistently appear in the correct sequence.
