Why is "Full Reverb" red?

[CMoore100]

I have a silly little podcast and my co-host and I use some not so great mics. For the history of ever I have always used DeNoise and Full Reverb on our audio to clean it up and it has always worked totally fine and gotten the job done. Our finished product has always been great (given the quality of equipment we're using currently, we are upgrading in the next couple weeks). 

However, the last week or so I haven't been able to apply the Full Reverb. It let's me add it to the effects rack and make the adjustments, but it's highlighted in red when I'm done. When I turn the effect on and off the audio has a little bit of a change but nothing like it used to. It's basically just turning the audio down a little and not really adjusting anything outside of that. What's happening?!

For reference we're just using basic cardiod microphones (like I said, we are upgrading very soon), feeding into Xenyx Q1202's via XLR and then into our desktop's via USB. The settings the soundboards aren't anything too extreme. Basically every setting on it is turned off except for gain and volume. 

Thanks in advance!

P.S. I know the mixer is off in the picture, I unplug it when it's not in use 😉

The thing you have to bear in mind about Full Reverb is that it's processor-intensive. When you first used it, you should (unless you disabled them) have seen this message:

And I have to tell you that for a podcast, Full Reverb is completely over the top. Your podcast's going out in a compressed format, and you simply won't get any benefit from all that stunning quality at all. If you want to use reverb, then go for a less processor-intensive one, like Studio reverb. You will be hard put to it to tell the difference - except when it comes to processing, which simply won't be an issue any more.

Why is it doing this to you? You probably haven't left it enough time to process your material - with a long file, this could take ages, and as mentioned above, for no real benefit. That's why it suggests that if you really want Full Reverb in the output, you have to pre-process it before mixdown, otherwise problems almost certainly will occur.
