How to reproduce:

1. Open attached project (configured.zip)
2. Build to iOS and run
3. Open the Memory profiler screen in Xcode
4. Select the Load from File option on the device
- Note that the memory usage increases by about 10mb
5. Select the Go Back option
- Note that the memory usage goes down
- Repeating this process does not produce different results
6. Select the Load from Memory option
- Note that the memory usage increases by at least 30mb
7. Select the Go Back option
- Note that the memory usage barely goes down
8. Repeat from step 6
- This causes the memory usage to ramp up until it reaches about 71mb at its highest
