Sometimes can't place rides/stalls

[xrgtmx]

Bug Description

Sometimes whenever on any of the five FFA servers, players can't place rides/stalls; invalid height error displays. The workaround is to exit the server and come back in. Usually, by then, the bug is no longer present for the time being.

To Reproduce

1. Go to any of the FFA servers and play normally.
2. Build a new ride and attempt to place the object down.

Expected Behavior

Rides/stalls can be placed down without any error.

Screenshots

Pending.

Platform info:

• OS: Windows 10, 64-bit
• Version: 0.4.10 (and back), x64

To avoid ambiguity, I will be referring to all heights as the raw-value height (0 to 255) and not the unit height (-7 to 120.5).

This is present in some form in all OpenRCT2 gameplay, singleplayer or multiplayer. It occurs when you attempt to place a ride at an odd height; although the ride preview will be shown at an even height, the yellow arrow can be shown at all integer heights. Usually when this happens, the invalid height error message is shown briefly and then the ride is placed at the even height that is the [arrow height + 1]. Sometimes the ride won't be placed at all and the error message will persist.

Examples:

• In the following image, the arrow is at an odd height, and the error message will be displayed at least momentarily.
  
• In the following image, the arrow is at an even height, and no error message will be displayed.

The error message also appears at least momentarily in all gameplay when placing a ride without using ctrl or shift to adjust the height (e.g. directly on the ground or water), even though the arrow appears at an even height. A workaround is to build with ctrl or shift, making sure that the arrow is at an even height.

Sounds like an upstream bug, then. Certainly none of my plugins pass along a invalid height error.
