Guardian Trinket not reviving archer ...

Hello when Co Oping recently with someone we were using the Archers and the Guardian trinket. A few Archers were killed and when my partner used the trinket to revive them nothing happened on my side. To me they all looked dead still. This is weird because I heard the trinket sound and know it had been used as was confirmed by the one I was playing with but the archers still remained dead. She however saw something different. On her side they were standing up again but something was still off, they were standing but not firing. In case this matters at all in solving this I had the archers in my loadout and she had the trinket in hers. So the archers being revived by her with the trinket were the archers that I had placed. We both got screenshots of this incident for use here. Hopefully this might help to fix this issue. Once the trinket reset time reset and it was usable again she used it and then after a second use it fixed it and they were revived on my side as well and now firing again. I'm thinking that we may have discovered a trinket bug here. It happened on a play through of The Tower on Endless mode.

Here's the screenshot she saw of the archers standing up but they wouldn't fire. As the pic shows to her they were revived. Well standing at least. Still wouldn't fire though: http://steamcommunity.com/sharedfiles/filedetails/?id=111172514

This is what I saw on my side. These 2 pics were taken at the same moments that she took that other one:

You can see by the chat all these shots were taken at the same time during this happening.

Thank You.
