I'm pretty sure the item does not retain any of the NBT of the item frame so it would not retain the potion effects either. Maybe edit your datapack to make item frames invulnerable.
The armor stand is probably in unloaded chunks, try loading the chunks (just move the player where the armor stand is) and see if the command succeeds then.
Is there a water source block below the flowing water? If I remember correctly water sources cannot form on top of flowing water.
Could you attach the crash log?
WAI
More information please
The firework stays attached to the player even after death/landing from my testing. This is obvious when giving yourself a firework with flight duration 127 (/give @s minecraft:firework_rocket{Fireworks:{Flight:127}}). This also occurs in 1.12.2.
This is probably due to render distance fog
WAI, they won't fix this because that spawning works on random ticks and it would be to complicated and unnecessary to change it for this case.
I don't believe this is a bug
Then you'd have to make every block a tile entity, which is unfeasible. I believe using CanPlaceOn:[] lets you interact with the block, although that requires an item to be held.
This is due to quasi-connectivity: Pistons can be powered by blocks 2 blocks above them, such as the redstone block it's pushing. This used to be unintended, but the redstone community used it for so many things that Mojang kept it to keep redstone machines working. While this is unintended, it will not be fixed because it will break many other things.
In order to figure out the issue and how to fix it, you must attach a crash log. Also, try to see if it's some other problem that can be easily fixed before reporting it as a Minecraft bug when it may not be.
This is caused because the item is losing durability. When ever the selected item changes, such as switching to a different item, changing it's nbt data, or changing the data/damage value, Minecraft will run the raising-an-item animation you see when switching items. You should update this report to the issue that damaging tools plays the animation. Also, the reason people don't take damage while blocking is because that was added as a feature.
The environment field is for your computer environment, such as OS and hardware, not for where in-game the bug happened. You also should be more specific about the issue and try to find the items or check the log and things like that. There is simply not enough information to work with, please be more specific and check to see if it actually is a bug first before reporting it.
Please provide a crash log
It seems likely they spawned during chunk population.
