Thank you, I didn't notice it, I went directly into the game after I wrote my reply.
EDIT: I looked at the patch notes, but I'm not sure this is the same bug, I could still replicate the bug on any map I played, it even happens on maps that have no team silos and only affects the GDI side.
While I was testing if it happens I noticed a few other minor bugs:
1. On the map 'Toxicity' one of the lamps on the eastern part of the Nod base is floating mid-air.
2. If you Right-click when using the Repair Gun, and then enter and exit a vehicle, the repair beam effect will appear, but it will be stuck to the location where you last used it.
