Thank you for replie.
We have updated MySQL 5.5.24 to 5.6.10
And vehicules still doesn't spawn. (Object_data seems don't work)
A little frustrated, we have reinstall all the lite package. But now nothing works... The server blocks in request of authentification. And after 40s of waiting : Somethin going wrong, please disconnect... (With no mods - No custom Dayz_code ect...just the basic package)
Maybe we doing it wrong...
Some help are welcome.
