"got lost" is indeed correct, and this form of its use is quite common, but it is considered bad style in formal writing. So yeah, it can be used, but to my ear it could be worded better. {shrugs} I'll go with whatever the creator decides .. odds are I'll never see the message anyway. ;)
(another after-thought: maybe its usage is fine, but I've still got the memories of my English teachers trying to beat me into not using "got" in this way.) :p
