Sub - VI preallouee clone seems to be intermittent who no longer respond. What's wrong?

Instead of looking long and hard for what would be a stylish vi I made my own. I don't understand why it does not periodically:

I have a situation where I want to delay the change of an integer value in a specific time. It is in a deterministic loop and cannot block. OK, so I made the vi joint 'whole Delay Change", which worked very well in the beginning.

After other changes to the code and multiple deployments to a crio 9068, this VI suddenly become unresponsive. While running interactively, the VI owner seems to work properly, the indicators of debugging on the wires leading to the correct vi display data, but this VI will not refresh its FP to correspond with the values linked to its terminals. If I run it by itself on the target and play with the front panel, it works as expected/designed.

I feel that I can use a while loop and registers at offset and it does NOT behave like a FGV (i.e. can be used in different places for unrelated purposes) so it environment. This problem occurred while it is configured for reentrancy preallouee clone.

What I am doing wrong? I hope that this will be part of an embedded reliable application and would be delighted to learn from a mistake in... I humbly accept all the suggestions on how to make this better/more intelligent/easier.

Thanks in advance.

You only change the integer if you happen to check when the time is EQUAL to the regular change time.  If you are unable to check it while a millisecond and then it will not change until that timer MS surrounds to 4294967295 ms, which is rather insensitive.  Normally for time-out calculations I subtract from the old times of the new time and check if it is greater than or equal to the timeout.
