When I try to travel from overworld to nether, after entering an address and pressing enter Stargate starts dialing sequence and immediately shuts down. I was able to determine that chunk unload event causes this issue (defined in SGCraft.onChunkUnload), but I only got this far because I'm not really good at wormhole physics. :(

Found and fixed the issue. I will be pushing a fix to this to forge/api-7 versions.

I have seen this issue as well though I thought it had something to do with Sponge. Are you using Sponge and what version of the mod are you using?

I have spotted this issue in 1.15.2-forge-release, but I've just made a test on db380f - the same issue occurs.

Right but you didn't answer whether or not you were using sponge.

If you're referring to THIS, then no, I'm not using it.

See, now this is helpful, now I can quit chasing my tail with Sponge. I will work on this shortly.

Sorry, I wasn't aware what Sponge was exactly (thought it was a separate platform).

Fixed, and posted here: https://ore.spongepowered.org/Dockter/SGCraft/pages/Home
