bugs when site searching via spells

[romis]

i've searched the site for this mentioned, and havent found it, possibly wrong key words. i also checked the bug shortlist and failed to find it mentioned. i apologize if its been brought up before.

I've noticed some bugs when attempting to search for magical sites with spells, which result, especially late game when trying boost my gem income, in ridiculously long amounts of time spent trying to micromanage my searches because the automation just doesn't work.

minor gripe, when attempting to search for magical sites, with spells, the default location is sometimes somewhere which can't have additional sites despite there being other unsearched places, or atleast i've never seen a capital with additional magical sites. i've actually seen this mentioned before a long time ago, but can't find it now. the result, either you waste a search on this location, or must manually work the targeting.

more problematic, when attempting to search monthly, it will stop despite locations being unsearched, for no discernable reason. when attempting to cast the spell manually, the default location is the casters location, already searched, meaning you have to hunt for the locations to search.
on occasion, but not always, i have noticed that these are locations searched by a mage in person, of higher or equal level as the one casting the spell, but obviously not completely searched, definetly not to the level 9 max the spell would do, or the level 4 some suggest as the actual cap for site finding. for example a level 1 death mage casting dark knowledge where a level 1 death mage has physically searched.
on occasion i have noticed these sites have a castle on them. i've noticed while mages can cast on a tile with an enemy occupied castle as long as you control the province, they won't by default, however it seems like the behavior could be continuing even after the castle is conquered.

also it would be nice if a system could be put into place where relevent, or atleast potentially relevent, information could be displayed when mouseover'ing a location to target it for a spell, for example when targeting for auspex, voice of aspu, etc, a list of how extensively that province has already been searched for magical sites. since as it stands now,(i'm obsessive compulsive here) i have to make a list of all unsearched locations to make sure i really have searched everywhere.
ideally only the information relevent to the spell being cast would be displayed, but if that is not possible, all potentially important information for any spell would do.
