Found bugs and limitations in RCT2

This page collects bugs and limitations that are present in the unmodified version of RCT2, but not mentioned in the readme file or in the GUI. For example, the limit of 128 rides per scenario does not count, since it's in the GUI of the scenario editor. The idea is that bugs and limitations like these may not be known to everyone since they are not that obvious.

The difference between a bug and a limitation is that a bug is unintended and a limitation isn't. Bugs introduced by OpenRCT2 should be reported under Issues.

Bugs

• On long queue lines, guest will sometimes enter the queue path without joining the actual queue. Instead, they will walk to the entrance and then return.
• Some rides are twice in the scenario editor selection list. Only one of them can be selected, but when you go to the next step and them back, the selected rides counter at the bottom will count both of them.
• When you select a saved ride with certain scenery, such as swamp goo, and hover it over the map without actually placing, the 'ghost' of the goo (the construction marker) doesn't go away. It can even be sold, although it hasn't cost you anything. This allows you to make a lot of money in a short time. A video with an explanation is here: https://youtu.be/MpSpAXuqRGo
• Alleged assembly bug.
• Peep AI pathfinding bug resulting in large numbers of park guests becoming 'lost' and walking in very tight loops. Causes a rapid degradation in Park Rating.
• Rides (.TD6 files) saved in the Rollercoaster Designer and in Scenarios are sometimes stored with the wrong heights and path clearances so they cannot be placed back in parks exactly as they were originally built.
• Underflow error causing 999 park rating if you have enough angry peeps.
• Litter bins don't get full. (Fixed with #763)

Limitations

• Only 255 rides and shops can be built in a saved game.
• Queues cannot get longer than 1000 people.
• There is a limit of 10,000 'sprites' in a saved game. (Sprites include guests, staff, ride vehicles, trash, vomit, balloons, and ducks)
• The maximum of years RCT2 supports is 8192. This means that 31 October, Year 8192 will be followed by 1 March, Year 1. Likewise, rides that are 8192 years old will be considered brand new the following year.
• There is a banner limit. It's unclear what the maximum number of banners is. But there also seems to be a bug at the calculation of it: https://forums.rctspace.com/index.php?showtopic=23825 Do you have a save which says you can't place more banners and you don't have placed that many banners then you can follow the following instructions to fix this: open the console window and enter "fix_banner_count" in the console window and press Enter. This will fix the banner count!
• There are two Powered Launch modes in RCT2. One where the train passes the station (like the Turbine in the Six Flags Belgium scenario) and one where it doesn't (the famous Shuttle Loop from RCT1). Which one is available depends on the track type and is not changeable using the GUI (but can be changed by hacking the SV6 file or using a trainer). (Both types available for every launched ride in OpenRCT2.)
• Although the Have Fun! objective is present in RCT2, it is not selectable from the GUI (but can be chosen by hacking the SV6 file or using the TRG Trainer). (Fixed in OpenRCT2.)
