Game slowdown when consuming

[DT V]

I’m feel sure someone must have discussed this in the past, but I do notice when reducing inventory that the game must have some sort of memory leak as it quickly deteriorates in speed and scrolling down hero lists to get to where hero’s to be consumed are falters and everything freezes for a few seconds and then freezes up again when trying to move heroes onto the pedestals for consumption.
I know the game stays in the same location on the list after a consume but sometimes an incomplete list comes back after a consume, I think that’s when a page of 40 + a new page becomes less than 40 so the page below is no longer needed.
Also when reducing inventory I tend to want to clear back all groups which involves moving between lists.
The only real solution I find for clearing the memory is to reset the tablet by powering it off and on again every time the scrolling become painfully slow.

Also as an aside there are moments when the game locks up just going into a battle, at the moment of selecting fight, and I notice it seems to happen most often when the game adds a stamina point (i.e. when the timer wants to add a point but the game is in the whirly wheel moment as it adjusts itself to show the combat)

It's an issue when order is reverted; on normal sorting, it takes a lot of time to get down, but then you can consume at normal speed, which is better if you have several things to consume.

What also works, at least for me, is reverse sorting, then choose the heroes to consume, then normal sorting, then hit consume, then reverse sorting and keep going; this hack isn't nice, but prevents the slowdown.

Take it in consideration, because if the past gives a clue about the future, performance issues aren't usually prioritized

Inverting the list also causes issues when consuming a number of different non-identical heroes where the consume again option where it’s still in inverted mode but displaying in normal mode so the scrolling is completely messed up and you have to invert the list which resets the listing to normal mode and display before inverting the list again.

Usually I wait until the inventory is maxed out and the slow down is obvious because I’m in the process of going through the list to tier up several different heroes sequentially plus switching into fortify mode to then fill fortify slots. Which can mean clearing out some 250 inventory slots.

This is part of why we've had to hard-cap the inventory size and can't go any higher. Performance issues. It's affecting several older devices and even some newer ones - the inventory reached critical mass and is causing these kinds of problems.

Memory leaks are the absolute hardest thing to track down in any program. But if this is happening consistently for you within consume/fortify, that may allow us to narrow down where we'll have to trace through to see what isn't cleaning up properly.

As the slowdown happens during the consuming of heroes to reduce inventory that the memory problem comes when refreshing the lists.
Causes are harder to identify, but as the lists are compiled and grouped by hero / Tier / XP when removing any hero / multiple heroes from the list the code needs to recompile itself and then correctly display the updated list.
Just a thought but I assume that as heroes are added during game play they are, I would imagine, added sequentially to available slots, but does the game rationalise the list by reordering / compressing the list moving hero data so that the next hero added is always at the bottom of the list or simply add to vacant positions?
