Ability to eject clan war defense troops and/or log who donated war castle troops

We just had our clan war chances plummet because someone donated lesser troops to defense instead of our planned high-end troops.

There is no logging, so no-one has any idea who did it, and of course, there is no way to dump the stupid things, so it cannot be fixed.

I don't know if it is possible, but could someone have joined our clan from the opposing team and donated them?

Something needs to be done about this because we cannot just kick the whole clan! :mad:

Quite frankly, if this sort of thing goes on, there is absolutely no point in participating in Clan Wars fullstop, being almost guaranteed to lose due to low defense.
