Reactor dumps heat vents, balancer, rods out when reloading chunk. The presented screenshot is already the third time the situation happens in a day. Server-sided mods and client-sided mods are listed below. Filtered extraction tubes and request tubes are connected to the reactors.

o.O could you try to provide a testable scenario?
At best would be without other mods, but first get it going with your modpack.

Because you are the first person EVER to report this kind of issue.
(Note it will be fixed but i need your help to fix it)

Sorry it's really difficult to reproduce the issue(i tried 3h in SSP and SMP but the problem cannot be produced again). I will try to reproduce the problem then make a new issue with test case. Thank you.

Update: After shutting down the server I copy the server files to my computer.







So basically you need to build a reactor like this. After setting the provider/requester tube, having clicked disconnect and reconnect then items drop.
Mod list(server/client)

To reproduce this, you might need to start a local server(i tries to reproduce locally but didn't work). We are running a forge-1.19.2-43.3.2 server.

Personally I think there is some issues about interaction between reactor and tube(provider/requester tube in this case), hope it might help you.

@Lee8950 it stays open. I will try it myself and at least have an honest look if there is a case.

Anyways it stays open until the next patch is out.
