Yeah I noticed this and don't have an answer yet, sure a fix will come up eventually.
Meanwhile its easy to resolve by disabling the effected folders...
#DBW/_0-Better pilots-v1/3do/Plane/ - disable folders beginning with B-17
-B-17E(Multi1)
-B-17E(USA) etc
We will keep an eye on this one - Better Pilots, a wonderful effort from barnesy12
https://www.sas1946.com/main/index.php/topic,25209.0.html is still very much a work in progress. It is a tremendously large project that does not as yet fix every plane. For this reason, the Better Pilots mod is on its own in Monty-07.
Monty-07 may also be easily disabled or re-enabled without effecting the rest of the TFM install. This is why, in JSGME, the lettering for Monty-07 remains black and not greyed out, as it is not effected by the other packs. Therefore you may de-install this pack and the Better Pilots mod for the time being until we have a more comprehensive application of it.
I imagine with a little more work and time it will be either replaced or patched, I just didn't notice the B-17 pilots until way too late. barnesy12 already has a fix for the JU52 pilots and I recommend people go and take a look at the thread and see how its going.
You can always rem-out particular folders as shown above (there are only a couple of aircraft that didn't work well I think), or just take it out, your choice.
