I was attacked by small spitters and (probably) also biters, but small spitters are ignored by flamethrower turret and thus destroy wall.

Loaded earlier save file, and haven't encountered bug again.

Am on the newest experimental release (2.1.17)

Welcome to the forum, and thank you for the report

hmmm, looks like its a similar issue as this: viewtopic.php?t=134141

The flamethrower is targeting the small biter, because it is within the 'prepare range',
and since it has the target priority, it is just patiently waiting for that small biter to approach...

I will look into a fix once the week starts, for now you can just shuffle the priorities to clear the annoyance
