Hi Peter,
A few things come into play here:
If you are using live filtering and choose a filter that does not apply to Adventures, then those caches will be hidden. For example, if you choose a D/T setting no labs will be returned because labs do not have D/T.
The geocaching.com API that Cachly uses will return all stages for non-sequential Adventures. For sequential Adventures it will only return stage 1 until you have finished that state. Then it will load 1 and 2 and so on.
I will look into the issues with auto load.
Let me know if you have any other questions.
