Actual behaviour

Many errors in different tables.
On table players:
randomizeshader tinyint NOT NULL DEFAULT '0'; (line 43)
Remove the ; and put a ,

On table player_mounts:
ADD PRIMARY KEY (player_id, mount_id) (line 357)
Should not have this "ADD"
And has 2 player_mounts creation code, line 354 and 382

On table player_shaders:
shader_id smallint(5) UNSIGNED NOT NULL DEFAULT 0 (line 405)
Need a , at the end

I think this is all. Thanks.
