Flipflop::StrategyError: Strategy '<UUID>' unknown.

where getting the following error every now and then when a strategy is turned off.
Flipflop::StrategyError: Strategy '<UUID>' unknown.

Backtrace includes:

/gems/flipflop-2.2.1/app/controllers/flipflop/strategies_controller.rb:26 in strategy
/gems/flipflop-2.2.1/app/controllers/flipflop/strategies_controller.rb:6 in update

This is pretty ambiguous.

flipflop version is 2.2.1
rails version is 5.1.4

I guess this can happen if your dashboard is open but you have changed the strategy definition(s) in the mean time. Could that be possible?

I was somewhat able to recreate this:

I disabled a Redis backed toggle(set to off) then without refreshing the page, a few minutes later turned it back on and got this error. Even when refreshing the page several times I got this error. On the third try It set and things were fine.
