i get this error not only with startWaterTask i get and with others, and same error 14000 lines... one time per day.

Maybe anyone know how to solve this problem?

The stackoverflow is a bug plaguing any aCis since at least 2y, it has been fixed with revert of movement system back to L2J.

Just a little addapt and is ok :D

Little? I'm many things changed in server core , so move all changes is hard :D

Thats why people use svn :D you can save your work even with a patch

SweeTs · September 17, 2016

Still progress is not lost. Take clean pack, the same revision, create SVN, replace with your actual sources and boom, you have diff patch with all your changes :)

wongerlt · September 18, 2016

Im use only notepad++ and ant (to compile). Im try to use eclipse but its very uncomfortable for me :/

And i see on latest version many changes, so i need rework all me codes to adapt ;)

Will be a lot of work from ~300 to ~360 :D

wongerlt · September 18, 2016

Oh why on latest version material, crystal_type, weapon_type are upercase? :D

SweeTs · September 18, 2016

Because they are not lowercase, obviously. It's an enum.

Tryskell · September 21, 2016

I force enum whenever I can.

wongerlt · September 21, 2016

To much work to move all server to new aCis version... Maybe anyone can tell me more about this movement system bug. Thanks :)

Example about bug that need target self to can move at start, but not all time.

You need to find the recursive call... ^^

You need to find the recursive call... ^^

You mean when function call self or call other function who call 1# function and it make while?
