deleting troops from cc should clear out the donatable count
problem:
now that you can clear out troops from your clan castle it should reset the number of troops that people can donate to you within that request - say you requested archers & someone gives you 5 barbs, you delete those barbs from your castle but the request in the chat still shows 5 space is already occupied. even if other team members are willing to give you all the archers you want, you still have to wait another 20 mins before you can "truly" fill your castle.
solution:
when you clear troops form your castle, the pending request in the chat should reflect the available space.
the issue/solution would also work for situations where you requested troops without realizing you had some troops in there from before that you didnt want.
gap:
once the request is filled it disappears, not sure how to cover that case? i suppose if it's within a reasonable amount of time, it could reappear and be available to only those people that didnt serve it the last time it came up. or maybe it might be better to just make the user wait if it's filled up all the way.
