[BUG][EDITOR-EXP] Loading old-format levels fails.

[namida]

Tested on V1.15; may also be on V1.14 but not completely confirmed.

When trying to load an old-formats LVL file, nothing happens after selecting the file.

Copy/paste from another topic,

There's two possible workarounds:

1. Use the old-formats "Flexi Toolkit" to build an old-formats NXP pack; then use the NXP conversion tool to convert the pack to new formats. This is a very tried-and-true method of conversion, but quite a hassle if you don't already have an NXP pack. There are also some minor issues - levels may lose backgrounds and/or talismans in the conversion. This will convert to the early-new-formats (V12.0.0 to V12.6.5, with backwards-compatibility up to and including V12.9.X). This is only applicable to old-formats LVL files.

2. Use V12.7.4-RC's "Cleanse Levels" feature on a pack that contains the level(s) you want to convert. You don't need to put together a proper pack with ranks and stuff - you can pretty much just create a temporary folder in NL's "levels" folder and throw LVL files into it, then run NL, select that folder, and run Cleanse Levels. This will convert to the V12.7.0-and-up format, which is more futureproof but doesn't work on the current stable version yet (a new stable version that supports it will likely be released around November 8th). This is applicable to any format NL can understand, although a levels.nxmi file must be used when dealing with formats other than NXLV or LVL.

Confirmed that this bug does not occur on V1.14, and it's fixed in V1.16 (included with NL V12.7.0-RC5).
