I have a basic event system in place and there are four choices: either relays do not fire correctly, VCE is broken, the default centerprint event is broken or these three do not work together at all. My money is on relays.
I have a control brick that once clicked fires one relay to 4 named bricks in 100ms intervals. One relay per one brick.
Once the named bricks get the relay, they modify a brick variable in the control brick by setting the value to 1.
Once clicked, after 500ms the control brick displays a centerprint with the first brick's value. 1000ms later a centerprint with the second brick's value and so on.
It seems to work the first time I click the control brick. If I click it again several seconds later usually the centerprints do not display the last 2-3 brick's variables. Oddly enough everything does seem to work. (The rest of the event system heavily relies on these 4 variables.)
I only have defaults + VCE enabled. Hosting a passworded internet server with only me on it.
