Hello, thanks, the solution to the slowness is to just download data for areas you are interested in from the links here:
https://www.megalithic.co.uk/topics.php?countries=1&kmldown=1
Or see the links from the right hand side of our search results pages eg. here
https://www.megalithic.co.uk/search.php?country=1&county=30&type=stories
The date from these is also more up to date with the latest corrections etc.
Something is not right. This message is just to keep things from messing up down the road
