drying rack duplicating items (after greg tech is added)

[mvdhoning]

If you have a drying rack and remove an item hanging from it i.e. a tinkers pickaxe it gets duplicated. You get on immediately in your inventory and the other (the duplicate) bounces on the ground and next gets picked up from te ground.

I noticed this behaviour after adding gregtech to my test world. First i filed a report at the gregtech forum but was there pointed to here, as they stated the bug was in tinkers.

Also the drying racks recipie was disabled after gregtech was added for a reason as duplication is not a wanted feature. Stil not sure if gregtech disabled it or tinkers or ...

Also possible related mod version info:
Forge 10.13.2.1236
Tinkers Construct 1.7.1c
Mantle 0.3.2jenkins184
Iguana Tinkers Tweaks 1.7.10-2.0.6
GregTech 5.0.6.04

There was a similar bug with casting blocks once. I ported the possible fix over to the drying rack. Test the latest jenkins build and please report back if it fixed the issue.

If it does, then it's a vanilla issue with entity spawning (possibly ask greg if he does something with that?). If it doesn't then its a gregtech issue, since both the drying rack and the tools are from tinkers and only interact with the Forge api. And work without problems with literally every other mod.

fixed :-)

So it was the same issue, k. Annoying.

got an answer from greg on the ic2 forum: ( http://forum.industrial-craft.net/index.php?page=Thread&threadID=7156&pageNo=2173 )

Overmind once told me about that Issue. It got ignored, because a Pack with GregTech seemed to cause it just a bit more often than any Pack without GregTech. It is a vanilla Issue, that is caused by Lag and Multithreading as far as he told me. Now it happened more often with GregTech, because I unificate ItemStacks right when they spawn, and with unification it causes a slight bit of more Lag than just regular spawning, what results in Items getting collected twice due to the reduced Collection Blocking Timer when collecting Stuff from anything that has this instant pickup Functionality.

Now randomly the item does not show up in the inventory: doing a relog (close the word and reopen it) fixes that and shows the item in the inventory. It was already there but somehow the inventory misses a refresh. Should i file a new bug on that?

Ah yes. I've heard about that lag-stuff before. So it's technically a vanilla bug that happens with Gregtech. ;)
The inventory-desync has the same reason, afaik. You should be able to fix it without relogging by simply applying the InventoryTweaks sort (middle click?) since that usually syncronizes the inventory. I don't think there's a way for me to fix that desync.
