Got Elemental while browsing on Amazon. I didn't beta so my experience is only a few days. I'm having a grand time.  Here are a few minor bugs that I have noticed and things that would be useful.  Note that any or all of these may be due to limited rules-reading or operator stupidity.

Bugs:

1.  Enchanter quest: go to enchanter's house with 3 midnight stones, get +1 sword.  However midnight stone inventory is NOT reduced by 3.

2.  Some areas with free space for building and beach access (slope to water) will not support build of harbor.  Other areas with free space for building but no beach access, e.g. inland town WILL support harbor (but you can't then build transport at the "inland harbor")

3.  One can load a unit on a transport, but there seems to be no way to command the unit to exit the transport, not even at another harbor, much less at an island without a harbor. Certainly activating the unit and clicking the up-arrow at the top of the unit circle-frame does not work.  How does one explore a new continent if you can't land a party on it?

4.  There seems to be a probability involved with successfully activating a crystal shard site.  Once crystal harvesting "construction" finishes, the site either becomes a barren black rectangle (failure?), a barren black rectangle with the crystal shard structure above (no idea?), or the original ground with the crystal shard structure above (success?).  Two things--one appears to get the crystal harvest in the display at the top of the screen even for sites that display as black rectangles.  Also, when one gets to the point of discovering new resources, these seem not to appear in land occupied by towns or other resources, but they do seem to appear beneath crystal shard locations. (I have a crystal shard with a gold deposit beneath it.

Useful things.

1. On the kingdom display it would be useful to be able to initiate communication with the monarch of each "kingdom" from the kingdom display in order to initiate trade or treaty. Initiating communication with minor kingdoms is a pain since you can't do so by right-clicking one of it's units and can only sometimes find the monarch.

2.  Exiting parties, especially large parties, from town, after healing is a pain, expecially because focus changes away from the town inhabitants.  How about activating the shift-key or something else to let one select units repeatedly, and then exiting all the ones selected at once.

Best, ADF
