If a Contact Sender is already present in the instance, a Contact Receiver may fail to respond to it for the first time after the avatar is loaded.
Behavior when the issue occurs:
・ The Receiver fails to react to a Contact Sender that already exists in the world. Even if a Sender is already active, the Receiver will not respond even if a third party's Sender becomes active afterward.
・ Toggling the Contact Sender off and then on again resolves the issue and makes the Receiver respond.
・ This occurs for both Remote and Local avatars.
The reproduction rate is over 90 percent, but the specific trigger conditions remain unclear. We tested this across multiple clients and found that results vary depending on the specific client; interestingly, some clients never experienced this issue regardless of the pattern.
During our experiments, all safety settings were disabled, and Show Avatar was enabled for all participants.
The avatar used for testing is as follows. Since it has a very complex structure, please feel free to ask if you have any questions regarding its setup.
Avatar ID: avtr_6257db3f-b32e-4ecb-9468-2e17e5a8c76c
Testing Method:
*This test is for verifying the Receiver on a Remote Player only.
  1. Two players wear this avatar. After the avatar loads, go to the ExMenu and enable SecretTalkSystem -> SecretTalkSystem Active.
  2. If a blue sphere appears above the avatar's head, the Receiver is correctly detecting the Sender.
  3. After confirming this, one player should switch to a different avatar and then switch back to this one, then repeat the same operation.
Technical Note:
・The Receiver is designed to be always active as long as the Animator is loaded.
・The Sender is enabled via "SecretTalkSystem Active" when the avatar is in the PlayerLocal state.
