After implementing the RLBase.reset! method for my environment im being told the method doesn’t exist.  
When checking in help mode, Julia asks whether i meant ‘reset!’ instead of ‘reset!’.  
Does anyone have a clue where that could be coming from?  
I’m sort of at a loss.

When explicitly calling RLBase.reset! everything works as intended, which is weird because RLBase.reward etc also work without the prefix, but for now the workaround reset!(env) = RLBase.reset!(env) seems to do the trick.

```julia
function RLBase.reset!(env::KniffelGym)
    env.dices = rand(1:6, 5)
    env.field_values = zeros(13)
    env.field_isempty = fill(true, 13)
    env.total_reward = 0
end

```
