I am very disappointed in the performance of vault. When ever I use vault I cannot place blocks and when I reload my server I cannot move, place blocks, break blocks and send chat or commands. If anyone knows an alternative to Vault, please tell me. I would not recommend vault to anyone else. Sorry.

None of the issues you described are at the fault of Vault. If the issues occur without Vault, it indicates that another plugin which depends on Vault is not functioning correctly.

Thank you turt2live
