Summary of the bug

Zombie Spawn Multiple time when more that one player is in the graves interface

Steps to Reproduce

Let someone die
Make the option to have the possibility to let more than one people open the grave
Loot the graves entirely when two or more people are in the grave
See that there is as much as zombie, as people who were in the grave the moment it has been looted

Expected Result

There should only be one zombie that spawns since the deceased person doesn't have "multiple corpses"

Actual Result

There is more than one zombie that spawn when many people are in the graves

Environment & Support Confirmation

• I confirm this issue occurs on the latest GravesX release or development build, not an outdated version.
• I understand that if I use development builds in a production environment and lose data, I will not receive support for that data loss.
• I understand that issues caused by other forks or Graves 4.9 are not supported here and may be closed.
• I am not running an outdated version of GravesX for this report.
• I am not using a Plugin Manager/Management plugin to load/unload GravesX. I understand these cause many behavioral issues and are not supported.
• I have checked existing issues and confirmed this is not a duplicate.
• I understand that reports with insufficient information or using outdated versions may be closed. I may open a new report after updating and providing full details.
• I am running a supported server type (Spigot, Paper, Folia, etc.) and not a hybrid jar (e.g. Mohist), which is not supported.
• I have tested with only GravesX installed (or with minimal plugins) to rule out plugin conflicts where possible.
• I am not just clicking checkboxes at random; I have read and understood the above.
