The type of column terrain is 'CHAR(2500)'.

Types in table room_terrain:

cid	name	type
0	id	INTEGER
1	room	TEXT
2	shard	TEXT
3	terrain	CHAR(2500)

I also tried to add options like --mysql-text-type MEDIUMTEXT --mysql-string-type TEXT , which does not help.

Hahaha, please forgive my ignorance. Besides, you may add a warning for invalid types

[Klemen Tusar]

Well, I was under the impression that that would have been handled by the incoming database, LOL.

And actually, the error message correctly informed you of the user error, so I'm not sure what more I could do here.
