Cant move after loading saved game

after opening a treasure chest near the church, all input doesn't work and you are stuck trying to loot the chest. loaded all files and the character is now stuck and cannot move

Hey i have found the chest stash and once i progress i'm like stuck in place and can't move at all and once i grab the logs and sails and anything else i'll be still be stuck and you know what that means i have found a Major bug so please make a Strong Major update to this game so that way it can be polished up and run smooth so please make an update to this game and i'll give you my ratings for this game ok?...

How do you fight? I am at the mission to kill 3 british troops. Cant equip a sword, cant fight and they just walk around doing nothing?

Who can tell me! Where is the item for the task of finding gold coins?! No hint at all! Can you fix the bug! BUGs are flying everywhere~
