TFTV only gives a fleeting warning about pending base invasions. Easily missed. If this is a deliberate design decision I don't like it.

you mean the info in the log, that is going to be removed. The base defense dynamic is changed in that the mission starts without warning, but you have 18 hours to complete it. The sooner you get to the base, the easier the mission. If you don't complete the mission in that time, the base will be damaged and infested, but you can recover it.

Anyhow, a base gets attacked. The game goes into the deploy squad screen, but because I have no squad to deploy there is no way forward (or back).

This bug is fixed in the last update; you can just hit the back button and do the mission later.

Thanks. I reloaded and was able to go back and get defenders to the base in time. This is a new type of base invasion, a welcome bit of variety!
