Thread safe script

[_12F_i-jeanm]

I am working on a script and I modify an ArrayList on two overrides methods. I get an exception. It works even if it is not good. I think, the exception come from the use of threads and my script is not thread safe.

Since I am not a C# coder and I do not know how you manage your threads. I wonder if a dev can give us some advices to use data in the right way with thread.

I join the script which give me exception and the actual version.
