I was playing the sortie mission today (08/30 Sortie 1 - Exterminate) and noticed that some of the barrels I was breaking were blowing up on me when they were clearly not explosive barrels... that is, until I started aiming at them to see the descriptive text. The explosive barrels (all of them) were colored the same as the normal breakable barrels. I have linked a screenshot from my steam account page to show you what I was seeing.
P.S. - I'm not sure if this bug report belongs here or not, so please move it as you see fit. I wasn't sure what other info would be useful. Let me know if there is any info you'd like that I can provide.
