The game doesn't allow me to complete the mission it gave me.

Yes unfortunately the range check got lost when some changes were made to the Spice Island missions.

When they changed the India and Spice Islands missions to target specific provinces I think they left out the range triggers as I've seen the same happen. In my case, I knew I wasn't close to having the range so I ignored the mission but it definitely is annoying and bugged that they will fill mission slots with missions you can't complete without more tech and/or ideas.

It's actually 'only' the Spice Island missions. It has also been fixed internally
