downloaded the addon on my laptop to test some stuff while "at work", but i cannot start the addon.

errors on logging in and reloading (all other addons except mdt, bugsack and buggrabber disabled, english client):
error 1: https://pastebin.com/CAT17sYU
error 2: https://pastebin.com/z5LWchqy

errors on typing /mdt and pressing enter ONCE:
error 3: https://pastebin.com/cjHeRws1
error 4: https://pastebin.com/vb75AF46

while pressing enter, the chat-line doesnt disappear (the /mdt i typed) and the addon opens (though without any visible map, see below). pressing enter a second time closes both the addon and the chat-line.

error 4 seems to be the same error as posted in #18, but since i got additional errors i opened a new issue. the map isnt showing either. error 4 seems to appear ~ 10 times per second while hovering over the location where the map should be (the now transparent area of the addon).

map not visible:

Try installing Mapster, it fixed this for me.
