Both of thouse bugs are easy to fix, problem for both Sunderland and Anson is in to high landing speed for them in FM when controled by AI, and i tested this in vanila game by adjusting their values and after making simple mod with fixes AI Anson and AI Sunderland land with no problems. Sunderland speed needs to be VminFLAPS 55.0 knots imsted 110knots as its now, and in Anson case it needs to be VminFLAPS 85.0 kmh insted 105kmh as its now. For Sunderland to be able to take off you just have to use 60%fuel, dont use full it dosent need it and it prevents him to lift off.
I even reported this bug on Sunderland and how to fix it to them 8 months ago, and still no word if this is tested, confirmed or in progress of fixing.
So even reporting stuff for Anson or other AI related problems like that i dont think they take seriously.
Making SP missions in Clod i noticed also that only Spitfire IIa out of all Spitfires in game needs to have +1600m manula made runway to land without going off airbases, also all AI Blenheims have same problem like this Spitfire IIa. Problem here is that AI dont use brakes when lands, he will go in taxi mode only when his speed is below 20mph ( you see this when he raises his flaps after he landed on runway) and on Blenheim and Spitfire II they take to long time to slow down to that speed, because of that they go off runways, And mission maker needs to make manula runways with atleast 1600m lenght for them, while other AI airplanes land on mutch shorter runways because they slow down below 20mph faster.
But thouse bugs are probably not high priority for TF as they are for SP only, and CloD comunity is MP mostly, so who knows when they will look at them. Maybe new FM changes that are being made for TF4.5 will fix this if they look at FM of AI only airlanes, i also reported bug on AI He-115 that prevents them beingused to take off from sea, as they bounce and explod, and how to fix it, but also no word if that is being looked as its only important to SP part of game. Regarding Spitfire II and Blenheims to long to slow down bugs are also related to FM of their engines, so i hope that will atleast be fixed for TF4.5 this year as thouse airplanes are human controled so TF may by acidente fix also AI behavior of them by adjustments they made to their FM files
As some one who build missions in Il-2 46 , making missions in CloD in state as its now and will probably be untill TF5 next year is nightmare and time consuming that it dosent even pay to play SP.
Example mission for Sunderland taking off from port, and you can see its landing problem there:
