Crashes when more than 3 inputs are setup in OSC settings

[secretfeature]

I am trying to send OSC messages between 2 game instances and it crashes on the receiving end. The messages look like any other message so I don't understand what about them would have this effect. If I send the same message from another source there is no problem.

Hi, I really need more info to help: your system, the log, a description of your system, etc.

After doing more tests I believe the crash occurs when I have more than 3 inputs setup in the OSC settings. I am on Windows 10, running 4.104. The crash log looks like this-

Access violation - code c0000005 (first/second chance not available)

If I stop the message coming from Reaktor it won't crash until I start them again. I am sending 6 different messages.

Do you use OscComponent and/or OscActor ? Or exclusively the "Inputs" way ?

[secretfeature]

I am now using both inputs and OSCComponent because I can't add any more inputs without the crash. I wasn't aware of OSCActor, Ill check it out.
