If you are holding a LAW, drop it, and run over another gun to pick it up, the second gun automatically drops as well. This makes it hard to exchange the LAW for another gun. I have experienced this bug in several past versions as well.

Here is a demo. http://llsc.us/members/Spectral/uploads/demo7.sdm
The first trial worked as it should for some reason, and the second trial occured as described above. What happened in the second trial occurs more frequently than the first.

Hmm...I thought it was happening with most weapons. It was when I was playing earlier, but I can't get it to happen anymore, not even with the law.

Although, another bug I've found is that when you drop a weapon while standing on top of another, the new weapon jams every time.

I'll check it out.

It happens with any weapon usually, when the time between dropping the first and picking the second is too short (seems like the solider is in "dropping mode" still)

Aha, it's a network issue. I don't know if this can be easily fixed.
