Hi,
Then, how do you know for sure that the wait action is missing? you can't not really verify this, but to judge the actual game behavior, so I would tend to think that something is playing funny when you publish that corrupts the intended behavior, but I don't think that the wait action would go missing.
It's a tricky situation... Have you trie to publish to other platform and does it performs as if the wait action is missing too?
bye,
Jean
