Why blademaster skill leap forward and backward cause error in all dungeon ?

as the title said

Always error, when blademaster try to leap forward and backward in all dungeon

why is that so ?

first i say thank you very much for the answer :laugh::thumbup1:

A screenshot or description of this error would be great :glare:

it's my own mistake :blushing:
perfect world client crash when i record it for documentation using video recording software
thank you for your attention and time :thumbup1::thumbup1::thumbup1:

Press Print Screen button on your keyboard and paste screenshot picture into Microsoft Paint then upload image? lol we can't help you without you TELLING us what the error says or when the error happens

the client now have no more error bug report when i record my exploring in dungeon without using leap forward and backward skill
only that two skill cause trouble when i record for documentation, others skill just fine
thank you for your attention and time, thank you :thumbup1::thumbup1::thumbup1:
