This actually worked.
I hope you don't mind if I ask another question.
I used to change the Claim time of horses inside the object_types table several year back when I created a server but now it looks like it has no effect what so ever. Some values are saved others are not.
I went with a command line that needs to be entered on every serverstart but this includes ALL horses. What means that CARTS are also claimed for several hours and claim members can't use them. (end yes, the dump.sql is renamed)
I decided to try to use your example of adding a line to the patch.sql.
Could you help me and tell me how to change the line so I can address a special ID inside a table? Because your suggested changes the value inside the entire table.
Theoretically this would be correct, or?
UPDATE `lif_1`.`object_types` SET `OwnerTimeout`='750' WHERE `ID`=1497;
