Long term ...
Too much worry about month to month issues.
They have concessions about equal to the size of the north sea.
They have the best partner in Africa in Tullow.
They proven several working petroleum systems - and will 100 or so targets defined (so far) does anyone expect each to be successful - with each they learn something more.
They are controlled by the Lundins. who have a marvelous track record of building wealth, and quite likely have never had as much to work with as they have here.
Petroleum developments take time, and this is a really big one. Let AOI, Tullow and Lundin to their thing and don;t worry about short term movements, or the issues that cause them. Give this a few years and it will prove itself to be a very pleasant investment choice - in my opinion
