When i tried to start again the server the console gave me 2 warnings: [warning] [tkldb] Unhandled type!! TKLDB is missing support for type 132 -- STOPPED reading db entries! [warning] [tkldb] Database invalid. Extra data found at end of DB file. |
|
|
I will provide you the "tkl.db" just in case that will help more. |
|
|
Thanks, shouldn't crash indeed. |
|

tkldb issue split off to https://bugs.unrealircd.org/view.php?id=5418 |
|
|
I'll see if I can have a look at this today for alpha3, otherwise I'll do it post-alpha3 though. |
