I took 4 Spidertrons out for a stroll on automatic firing (3 of them were following the main one which I was driving). There were some biters and the Spidertrons fired explosive rockets at them. The biters were inside dense forest and therefore when the explosive rockets landed, the trees were destroyed and I got the Run, Forrest, run achievement.

This should not have happened as the Run, Forrest run achievement requires 100 trees to be destroyed by "impact" and this should not have counted.

The mods loaded in this save were:
base 1.1.59
EvoGUI 0.4.601
helmod 0.12.9
resourceMarker 0.7.28
safefill 1.0.10
These should not have influenced this bug.

I have since reproduced the bug in a seperate save using explosive rockets, C targeting, and only a single spidertron. This was achieved on the 1.1.60 experimental version with the following mods:
base 1.1.60
assemblyanalyst 1.1.11
creative-mod 1.7.2
flib 0.10.1
EditorExtensions 1.12.10
These should also not have influenced this bug.

Things I have noticed:
It (most likely) doesn't matter what the Spidertron is targeting or if it is manual firing or automatic firing.

I have included a log file for the session of the reproduction and a screenshot detailing the process.

Thanks for the report. It's now fixed for the next release.
